Analysis on the Geological Characteristics and Mineralization Regularities of the Fluorite Deposits in the Taishanmiao Area,Henan Province
摘要
Abstract
In order to strengthen the research work on the prospecting of fluorite ore in the Taishanmiao area,this paper systematically summarizes the mineralization laws of fluorite ore in this area through a comparative analysis of the geological characteristics of typical fluorite deposits in the region.It is believed that the fluorite deposits were formed in the Early Cretaceous period and are closely related to the Taishanmiao rock mass.The ore bodies are mainly distributed in the inner contact zone between the Taishanmiao rock mass and the surrounding rocks.The NE-trending and nearly EW-trending faults are the main ore-bearing structures.The Taishanmiao rock mass provides an important material source for fluorite mineralization.The ore-forming fluid belongs to the H2O-NaCl system fluid with low temperature,low salinity and low density.The deposit type is a medium-low temperature epithermal hydrothermal deposit controlled by faults.According to the research results,a field investigation of the favorable mineralization areas in the Taishanmiao area was carried out.Four fluorite ore bodies were discovered near Songmengou.The preliminary estimated resource quantity of CaF2 is 250,000 tons,reaching the scale of a medium-sized fluorite deposit,which has a good prospecting potential.关键词
