Prediction of Hidden Granites in the Luziyuan Area of Yunnan Province and the Prospecting Direction

The Fe-Pb-Zn-Cu polymetallic deposits in the Luziyuan area, are of a sedimentary-reformed type related with magmatic hydrothermalism. Previous researches have suggested that the mineralization is closely related to the hidden granites, but little is known about these granites including their burial depth and scale, which has limited the establishment of prospecting models and the optimization of prospecting targets. Geophysical methods have a great exploration depth, and have played a unique role in the prediction of hidden granites. It is shown that granites have low density and high resistivity,

The inciderce of stem rot and ear rot of Yayu 891 was high, so Yayu 891 should not be planted in the region. [Conclusion] Shenyu 10 had a high yield, suffered few diseases and had strong stress resistance, so it can be popularized widely in the region.

Concealed porphyry delineation based on nonlinear three-dimensional densitydifference inversion: An example in the Beiya mine area, Western Yunnan, China

Intermediate acid-complex rock masses with low-density characteristics are the most important prospecting sign in the Beiya area, of western Yunnan province, and provide a physical basis for good gravity exploration. It is usually difficult to obtaining solutions in connection with actual geological situations due to the ambiguity of the conventional gravity-processing results and lack of deep constraints. Thus, the three-dimensional (3D) inversion technology is considered as the main channel for reducing the number of solutions and improving the vertical resolution at the current stage. The current study starts from a model test and performs nonlinear 3D density-difference inversion called “model likelihood exploration”, which performs 3D inversion imaging and inversion of the known model while considering the topographic effects. The inversion results are highly consistent with those of the known models. Simultaneously, we consider the Beiya gold mine in Yunnan as an example. The nonlinear 3D densitydifference inversion technology, which is restricted by geological information, is explored to obtain the 3D density body structure below 5 km in the mine area, and the 3D structure of the deep and concealed rock masses are obtained using the density constraints of the intermediate-acid-complex rock masses. The results are well consistent with the surface geological masses and drilling-controlled deep geological masses. The model test and examples both show that the 3D density-difference nonlinear inversion technology can reduce inversion ambiguity, improve resolution, optimize the inversion results, and realize “transparency” in deeply concealed rock masses in ore-concentrated areas,which is useful in guiding the deep ore prospecting.

云南省自然保护地现状特征及其体系重构规划策略

自然保护地高质量发展需要科学有序开展省域和全国2个层级的自然保护地归并整合及体系规划,以云南省域自然保护地数量、面积及空间分布特征为客观基础,提出体系规划策略“完备制度、科学规划”。对云南省各类各级自然保护地及16个州市自然保护地资源进行数量和空间分布的梳理、归纳分析,从现象到本质凝练特征,提出体系重构规划策略。结果发现:全省11种类型的自然保护地由7个主管部门管理,分布于全省16个州市约377处,面积约55277 km^(2),占全省土地面积约14%。各种类型的自然保护地数量、面积差异极大,以林业和住建行政主管部门为管理主体,分级和分级标准不确定。空间分布特征以“哀牢山—无量山”为界限,以西有创建国家公园等大型自然保护地的基础,以东则适合构建自然公园体系。一是以体系思维、系统完整性为重构逻辑。二是“哀牢山—无量山”以西的滇西、滇西南、滇西北是国家公园建设的关键区域。三是“哀牢山—无量山”以东的滇中、滇东、滇东南、滇东北等地则亟待完善自然公园体系。展望由地表覆盖类型、距道路遥远度、人口分布密度、距聚居点遥远度、生物物理自然度等维度识别云南省域最不被打扰的地理空间及客观存在的相对较荒的区域作为省域自然保护地扩容的备选资源。

滇东石林地区早—中二叠世Globivalvulina有孔虫动物群

对云南石林地区早—中二叠世地层剖面中的Globivalvulina(球瓣虫属)化石系统研究结果表明,栖霞组含16种,茅口组含有13种,两组中物种相似度可达92%。种级分异度变化显示,栖霞组的种以增加趋势为主,茅口组则以减少为趋势。总体上这一时期Globivalvulina动物群物种上升高峰仅有一次,出现在栖霞组中上部;而下降高潮有两次,第一次出现于栖霞组上部与茅口组底部界线附近,第二次是茅口组顶部。后一次下降幅度远大于前者,可能与中二叠世末期有孔虫动物群演化事件有关。
