Highlights

During the 1990s，with the deepening of research and exploration of carlin-type gold deposit in China on the basis of the connotation of carlin-type gold deposit，some gold deposits were discovered and redefined as carlin-like gold deposits.This is a class of gold deposits that show similar geological characteristics to the carlin-type gold deposit，but their geochemical characteristics are obviously different.The Zhaishang gold deposit located in the western part of the Li-Min metallogenic belt within the western Qinling Mountains is a very important carlin-like disseminated gold deposit.Since it was discovered through geochemical anomaly information and civil mining information in 2 000，many workers have carried out geological，geochemical，geophysical，remote sensing，engineering and other aspects of exploration，as well as researches on mineral composition，texture and structure of rock，orebody distribution，fluid source and ore-forming conditions，showing the superior metallogenic geological conditions and great prospecting potential of the deposit.Based on a large number of field work data and analysis of ore-forming characteristics in the mining area，we mainly studied the No.31 vein and the Zhamashu ore section in the South ore belt，taking the measurement and analysis of structural traces of different scales as the basis.On the basis of the analysis of the ore control law of the structure，the “three in one” ore-forming model of ore-forming geological body，ore-forming structure，ore-forming structural plane and ore-forming characteristics was summarized to guide the prospecting systemati-cally.The results of field observation and statistical analysis on the structural fissures of the Zhaishang gold deposit show that the most developed joints are in the NW-SE direction of 106°~137°，and the joints in the NE-SW direction of 196°~229° come second.It is indicated that the SN-trending compressive stress in Indosinian period，which is an important structural period of the gold deposit，formed most of the joint fractures of the deposit.And the deposit is mainly formed in Indosinian and Yanshanian tectonic movements，the orebody is controlled by folds，faults and strata.In Yanshanian period the deposit was mainly controlled by NE-trending positive torsional stress，which led to the successive activity of NW-trending structure formed in the Indosinian period，the emplacement of magmatic hydrothermal fluid along fractures，the mixing of atmospheric precipitation，and the superimposition of mineralization on the early orebodies.

河南完成历史遗留矿山环境治理23万亩

2021年1月，记者从河南省自然资源厅获悉，“十三五”时期，河南省通过露天矿山整治、绿色矿山建设和废弃矿山治理，共完成历史遗留矿山环境治理23万亩，恢复耕地77 445亩，为“十二五”时期的2倍；恢复建设用地36 495亩，为“十二五”时期的2.5倍。

从2018年开始，河南省陆续开展了露天矿山生态环境综合整治、绿色矿山建设和废弃矿山治理，其间始终坚持“宜建则建、宜耕则耕、宜林则林、宜景则景”的原则，一矿一策，推动矿山生态环境巨变，促进矿山企业转型发展，为建设“山青、水碧、林郁、田沃、湖美、草茂”的美丽河南作出了积极贡献。

河南省对露天矿山“关小上大”，关闭了一批建筑石料类小型矿山，目前全省露天矿山数量已从992个减至605个。同时，持续加大绿色矿山建设，实行边开采、边治理，全省76家矿山纳入全国绿色矿山名录，数量居全国第一；111家矿山提交第三方评估申请，54家通过了省级绿色矿山评估，其中17家达到了国家遴选标准。
