Major Research Achievements Of 2013

[ 05-12-2015 ]

(1) Marine fossils discovered in the upper part of the Late Permian Linxi Formation in the Xingmeng area: The study shows that the Xingmeng area in Inner Mongolia had a marine or primarily marine sedimentary environment even until the Late Permian. This finding gives new and reliable evidence for identifying the eventual close of the Xingmeng sea basin and would facilitate adjustment of the thoughts and deployment of exploration for ordinary oil-gas, shale gas (oil) and other metallic and nonmetallic ores in Late Permian strata in the Xingmeng area.
(2) A discovery in ore prospecting: The Xiongmei porphyry copper deposit was found in the BangongNujiang suture zone in Tibet, which has potential to become a large-sized ore deposit. This could promote our understanding for mineral exploration in the Tibet area.

(3) New understanding regarding the super-large Gejiu Sn-Cu polymetallic deposit in Yunnan: Research revealed that mineralization and contemporaneous magmatism bear a close genetic relationship in the concentrated area of tin-polymetallic deposits in the study area. This deposit was considered to have a magmatic-hydrothermal genesis rather than syngenesis.

 (4) Metallogenic process of W-Mo-Cu deposits related to Caledonian granodiorite-porphyry in the Dayaoshan area: The study pointed out that there occur a series of porphyry-skarn-quarte vein type W-Mo-Cu ore deposits related to Caledonian granodiorite-porphyry in the Dayaoshan area in Guangxi.
