铜陵地区微量元素铊与金在成矿中的相关性初步探讨

古铜陵地区是长江中下游成矿中重要的多金属成矿区,有着独特的多位一体、"层".带"结合、多矿种、多种成因类型复合的成矿地质环境,产生了丰富的接触交代与层控式夕卡岩-热液充填交代的块状硫化物型的铜、金、银、硫等内生矿产,成为国内外地学研究的热点地区.本文从铊元素的地球化学研究探寻其作为金(铜)矿床的探途元素的可能,从本区一些主要矿床中过铊与金(铜)相关性的研究,得出铊与金(铜)密切正相关的结论,并进行了微量元素铊在找矿方面应用的一些初步探读者论坛,指出下一步找矿方向及预测靶区.

PRELIMINARY STUDY OF RELEVANCE OF TRACE ELEMENT THALLIUM WITH GOLD DURING MINERALIZATION IN THE TONGLING AREA

The Tongling area is an important polymetallic metallogenetic province along the middle-lower Yangtze River.It becomes a hot spot for geological research at home and abroad for its unique ore-forming geological conditions such as multiple layers of ores in one body,combination of ore beds and belts,composition of many ore types and genetic types,which thus result in abundant contact-replacement,strata-bound skarn-hydrothermal filling massive sulphide endogenetic deposits of copper,gold,silver and sulphur.This paper discussed the possibility of using thallium as an indicator for searching gold(copper) deposit from geochemical study of thallium and concluded normal relevance of thallium with gold(copper) based on study of some major ore deposits in the area.It also involved application of trace element of thallium in ore prospecting and pointed out the direction and prognostic target area.
