Gardaneh Salavat porphyry copper system: Is it about metal endowment or fertility of the porphyritic intrusion?

Gardaneh Salavat porphyry copper system is located in the northwest of Iran. It comprises a quartz diorite to diorite porphyritic intrusion that created extensive alteration haloes in the host rocks. Despite all technical considerations, the exploration activities did not yield to ore discovery. As the matter of fact, all of the geological,geophysical, and geochemical characteristics of a porphyry Cu-Au deposit exist but there is no economic mineralization. Detailed examinations suggest that the only reasonable explanation can be related to the infertility or low metal endowment of the porphyritic intrusion. The reasons include(1) anomalous ranges of Cu, Au, and Mo rather than economic ore grades,(2) weakly development of potassic alteration,(3) probably sulfur saturation of magma that occurred before intrusion emplacement in the host rocks, and(4) probably low metal endowment in the regional scale and the lack of known porphyry copper deposits in close neighborhoods. It is tried to test the proposed hypothesis with the introduced fertility indicators based on major and trace element geochemistry. However,current fertility indicators could not prove or reject the proposed hypothesis for Gardaneh Salavat porphyritic intrusion because of the high-K calc-alkaline to shoshonitic nature of the intrusive rocks together with the unavailability of relatively fresh/unaltered samples. This case study is notable to examine because(1) it shows that characterization of fertile from barren intrusions seems to be as important as vectoring towards concealed porphyry copper deposits, especially while dealing with deep exploration targets that are associated with high financial risks, and(2) it highlights the inefficiencies and uncertainties in introduced magma fertility indicators for porphyry copper intrusions. As a result, it is of high importance to conduct an overarching investigation on other possible fertility indicators as a fundamental need for the future of the exploration industry.

Based on the household livelihood endowment theory and the survey of 367 farmer households in Anhui,Hubei,and Sichuan in 2016,and using the orderly multi-category logistic model,the behavioral decision of farmers in the land circulation was discussed to explore the key parameters influencing the land transfer-out.

Therefore,increasing the allocation efficiency of household livelihood endowment has important policy value and practical significance for eliminating unreasonable land circulation and promoting large-scale agricultural production.

Influences of population characteristics and natural resource endowment on renewable portfolio standard schedule design

Renewable portfolio standard （RPS） schedule requires a specified percentage of renewable electricity development by a specified date, and therefore directly determines the pace of renewable electricity in one area. The article aims to explore the ways the natural resource endowment and population characteristic affect the adoption of a RPS schedule. We used logistic regression to analyze the data of RPS dynamic schedules of 29 states and Washington, D.C. in the United States. Results show that local renewable potential and the interaction performance between citizen ideology and the league of conversation voters scoreboard are main factors affecting the choice of an RPS schedule, and the effect of the interaction performance between citizen ideology and LCV scoreboard has a higher significance. The finding suggests that strategies for developing renewable energy should be based on resources rather than economical level, and nublic education for environmental protection should be emphasized.

Relationship between Economic Development,Resource Endowment and Soybean Export Dependability

The dependability of world major soybean exporters was measured and its influencing factors were analyzed through constructing the export output elasticity indicator.It was found that since 2010,among the world major soybean exporters,the dependability of Brazil,India,Russia and Ukraine increased,the dependability of Argentina and Paraguay dropped,while that of Canada,the USA and Uruguay was basically stable.Among the influencing factors of the dependability,the increase in international soybean prices and abundance of cultivated land resources are helpful for increasing the dependability,while the increase of population and improvement of economic development will reduce the dependability.China should reduce its dependence on countries with low export dependability,and actively develop production cooperation with import source countries to promote their dependability.
