Geological characterization and exploration potential of shale gas in the Carboniferous Jiusi Formation,northern Guizhou and Yunnan provinces,SW China

Dark mudstones and shales of the Carboniferous Jiusi Formation are widely developed in northern Guizhou and Yunnan provinces, SW China. However, the distribution, reservoir characterization, and exploration potential of organic-rich shales in this area are yet to be quantified, thus limiting the prospect of shale gas in this area. This study investigates the basic geological conditions of Jiusi shale gas, using core data, well-logs, and some other test data, obtaining the following results. The organic-rich shales are mainly composed of deltaic-to-shallow-shelf deposits, with thickness ranging from 0 to 450 m, and above 350 m around the subsidence center. The organic matter is mainly type Ⅱ kerogen with TOC content of mostly 1%–2%, indicating a moderate maturity. The argillaceous shale reservoirs are indicative of strong heterogeneity, high clay minerals content, low porosity, low permeability, high specific surface area, and relatively developed secondary porosity. The gas-log anomaly intervals obtained from the survey wells have a cumulative thickness that is apparently greater than 200 m, and a few shale intervals showing high desorbed and adsorbed gas contents. Due to complex structures in the study area, conditions responsible for shale gas occurrence and trapping are generally moderate. However, areas having wide and gentle folds with moderate depth of burial reveals relatively favorable conditions of hydrocarbon traps. In contrast with typical marine-continental transitional shales, the Jiusi shale have better geological conditions for shale gas preservation. The analysis of the geological framework and hydrocarbon potential of Carboniferous Jiusi Formation provide more insight for the exploration of Carboniferous shale gas in southern China.

Study of the Seismogenic Structure of the October 12^(th),2019 MS5.2 Beiliu Earthquake,Guangxi,China

On October 12th,2019,a MS5.2 earthquake occurred in Beiliu City,Guangxi Zhuang Autonomous Region,China,with a focal depth of 10 km. The epicenter is located in the junction of Guangxi and Guangdong where the moderate-strong earthquakes are relatively active. The highest intensity of this earthquake is estimated up to Ⅵ besides the isoseismic line showed an ellipse shape with a long axis trend in the NW direction.The aftershocks are not evenly distributed. The parameters of the focal mechanism solutions are: strike 346°,dip 85°,rake 19° for the nodal planeⅠ,and strike 254°,dip 71°,rake 175° for the nodal planeⅡ. The type of the coseismic fault is strikeslip. After analyzing these results above and the active faults near the epicenter,we get that the nodal planeⅠ is interpreted as the coseismic rupture plane and the BamaBobai Fault is a seismogenic structure of MS5.2 Beiliu earthquake.

Malaria from hyperendemicity to elimination along international borders in Yunnan, China during 2003‒2020: a case study

Background: Border malaria is one of the most intractable problems hindering malaria elimination worldwide.Movement of both the human population and anopheline mosquitoes infected with Plasmodium spp.can cause cross-border malaria transmission.The Yunnan border area was still hyperendemic for malaria in the early part of this century.The objective of this case study was to analyze the strategies,interventions and impacts of malaria control and elimination in the Yunnan border area.Main text: A total of 10,349 malaria cases and 17.1 per 10,000 person-years of annual parasite incidence(API)were reported in the border area in 2003.Based on natural village-based stratification,integrated interventions,including mass drug administration for radical cures and preventive treatment,clinically presumptive treatment of all febrile patients for malaria and indoor residual spraying or dipping bed nets with insecticides were successfully carried out from 2003 to 2013.The overall API was reduced to 0.6 per 10,000 person-years by 2013,while effective cross-border collaboration interventions dramatically reduced the malaria burden in the neighbouring border areas of Myanmar.From 2014 forward,the comprehensive strategy,including universal coverage of surveillance to detect malaria cases,a rapid response to possible malaria cases and effective border collaboration with neighbouring areas,successfully eliminated malaria and prevented reintroduction of malaria transmission in the Yunnan border area.Conclusions: In Yunnan malaria burden has successfully reduced by dynamically accurate stratification and comprehensive interventions;and then the region achieved elimination and prevented reintroduction of malaria transmission through intensive surveillance,rapid response and border collaboration.Other border areas should perform their own intervention trials to develop their own effective strategy.

青藏高原边缘区地震灾后的经济韧性及恢复效率——以汶川Ms 8.0地震极重灾区为例

The border areas of the Tibetan Plateau and the neighboring mountainous areashave a high incidence of earthquakes with a magnitude greater than Ms 5.0, as well as havinga dense distribution of geological disasters such as collapses, landslides, and debris flows.Revealing the post-disaster economic development and recovery process is very importantfor enhancing disaster prevention and response capacity in order to formulate control policiesand recovery methods for post-disaster economic reconstruction based on economic resilience.Using long-term socioeconomic data and the autoregressive integrated moving average(ARIMA) model, this paper calculated the economic resilience index of the areas mostseverely affected by the Wenchuan Earthquake of 2008 and adopted the improved variablereturns to scale (VRS) date envelopment analysis (DEA) model and the Malmquist productivityindex to analyze the efficiency and effect of annual post-disaster recovery. The resultsshow that: (1) the economic resilience index of the areas most severely affected by theWenchuan Earthquake was 0.877. The earthquake resulted in a short-term economic recessionin the affected areas, but the economy returned to pre-quake levels within two years. Inaddition, the industrial economy was less resilient than agriculture and the service industry. (2)The comprehensive economic recovery efficiency of the disaster-stricken area in the yearfollowing the disaster was 0.603. The comprehensive efficiency, the pure technical efficiency,and the scale efficiency of the plain and hilly areas were significantly greater than those of theplateau and mountain areas. (3) The annual fluctuation in total factor productivity (TFP) followingthe disaster was considerable, and the economic recovery efficiency decreased significantly,resulting in a short-term economic recession. The TFP index returned to steadystate following decreases of 33.7% and 15.2%, respectively, in the two years following thedisaster. (4) The significant decrease in the post-disaster recovery efficiency was causedmainly by technological changes, and the renewal of the production system was the leading factor in determining the economic resilience following the disaster. With the decline in thescale of economic recovery following the earthquake, long-term economic recovery in thedisaster-stricken areas depended mainly on pure technical efficiency, and the improvement inthe latter was the driving force for maintaining the long-term growth of the post-disastereconomy. Therefore, according to the local characteristics of natural environment and economicsystem, the disaster-stricken areas need to actively change and readjust their economicstructures. At the same time, attention should be paid to updating the production systemto enhance the level of technological progress and give full play to the scale effects oflarge-scale capital, new facilities, human resources, and other investment factors followingthe disaster so as to enhance the impact of economic resilience and recovery efficiency inresponse to the disaster.

Assessment of malaria control consultation and service posts in Yunnan, P. R. China

Background:This paper seeks to assess the function of malaria control consultation and service posts(MCCSPs)that are located on the border areas of Yunnan province,P.R.China,as a strategy for eliminating malaria among the mobile and migrant population in these areas.Methods:A retrospective descriptive analytical study was conducted.Blood smear examinations conducted at all MCCSPs in Yunnan from 2008 to 2014 were analysed.A cross-sectional survey was conducted in 2014 to understand how the MCCSPs function and to elucidate the quality of the blood smear examinations that they conduct.Results:Out of the surveyed MCCSPs,66%(39/59),22%(13/59),and 12%(7/59)were attached to local township hospitals,village health clinics,and the county centre for disease control and prevention or private clinics,respectively.More than 64%(38/59)of the posts’staff were part-time workers from township hospitals and village health facilities.Less than 31%(18/59)of the posts’staff were full-time workers.A total of 35 positive malaria cases were reported from seven MCCSPs in 2014.Four MCCSPs were unable to perform their functions due to under staffing in 2014.There was a small fluctuation in blood smear examinations from January 2008 to June 2009,with two peaks during the period from July 2009 to October 2010.The number of blood smear examinations has been increasing since 2011.The yearly mean number of blood smear examinations in each post increased from 44 per month in 2011 to 109 per month in 2014,and the number of positive malaria cases detected by blood smear examinations has declined(χ^(2)=90.67,P=0.000).The percentage of people from Yingjiang county getting blood smear examinations increased between 2008 and 2014,while percentages of the mobile population including Myanmar people,people from other provinces,and people from other Yunnan counties getting blood smear examinations decreased.Conclusion:MCCSPs face challenges in the phase of malaria elimination in Yunnan,China.New case detection strategies should be designed for MCCSPs taking into account the current trends of migration.

Poverty and malaria in the Yunnan province, China

Poverty and malaria appear to have an intertwined link.This paper aims to define the relationship between poverty and malaria in Yunnan,China,and to make recommendations for future research in this important area.Data on malaria prevalence and the population’s income in each county between 2005 and 2010 were obtained from the Yunnan Center for Disease Control and Prevention and the Yunnan Bureau of Statistics,respectively.Geographic mapping shows an apparent spatial convergence of poverty and the incidence of malaria at a county level,and suggests that poverty may be one of the drivers of malaria transmission in Yunnan.Future research should focus on:1.measuring and quantifying the relationship between poverty and the malaria burden at the individual,community,county and regional level in Yunnan;and 2.developing the GIS-based spatial decision support system(SDSS)framework in malaria endemic areas,particularly along the border areas in Yunnan.
