广西(1:5万)融水县幅(G49E019006)区域地质调查

Regional Geological Survey of Rongshui County Sheet(G49E019006) in Guangxi(1:50,000)

本设计初步厘定桂平组、临桂组、大埔组等27个地层填图单元。设计的主要内容为区域地质调查和区域矿产调查设计两部分。①区域地质调查设计内容:以青白口系地层为界初步划分为新老地层填图分区4个,完成1:5万区域地质填图2230km2。②区域矿产调查的包括矿点检查和异常查证,依据1:20万融水化探组合异常及成矿地质条件选定3处异常重点查证区,查证技术方法为1:2.5万地质填图,对于成矿条件好的重点异常查证区设计1:1万地质填图和1:5000化探剖面。针对新寨附近铁矿点、公景褐铁矿点、大塘锰矿点等几处重点检查,矿点布置适当的槽探工程。

This design preliminarily defines 27 stratum mapping units, such as Guiping Formation, Lingui Formation and Dapu Formation. The main contents of the design are regional geological survey and regional mineral survey and design.① Regional Geological Survey Design Content: The Qingbaikou Formation is initially divided into four new and old stratum mapping zones, and 1:50,000 regional geological mapping is completed in 2230 km2.② Regional mineral survey includes mineral spot inspection and anomaly verification. Three key anomaly verification areas are selected according to 1:200,000 combination anomalies of melting water geochemical exploration and metallogenic geological conditions. The verification technology is 1:25,000 geological mapping, and 1:10,000 geological mapping and 1:5,000 geochemical exploration profile are designed for key anomaly verification areas with good metallogenic conditions. In view of the key inspections of iron ore points near Xinzhai, Gongjing limonite points and Datang manganese mine points, proper trench prospecting works are arranged at the mine points.
