摘要
蛤蟆岭金矿是近些年来铜陵地区南部实现的找矿新突破,在O/S界面发现了斑岩型金铜矿。茗山岩体位于蛤蟆岭岩体东部。为了研究茗山岩体周边及深部的含矿性,本文对蛤蟆岭岩体、茗山岩体进行岩石学、岩石地球化学方面的对比。研究结果表明,蛤蟆岭岩体、茗山岩体岩石为高钾钙碱性系列,其源岩可能来源于深部地幔。通过对比,笔者认为在茗山岩体成矿条件与蛤蟆岭岩体相似,茗山岩体周边及深部存在斑岩型矿床的可能。
Hamaling Gold Deposit is a new breakthrough in prospecting in southern Tongling in recent years.Hamaling gold-copper deposits were found at the O/S interface.Mingshan pluton is located in the east of Hamaling pluton.This paper compares the petrology and geochemical characteristics of the Hamaling pluton and the Mingshan pluton.In order to study the ore bearing characteristics of the surrounding and deep Mingshan pluton,this paper compares the petrology and geochemical characteristics of the Hamaling pluton and the Mingshan pluton.The research results show that the rocks of Hamaling and Mingshan rocks are of high-potassium-calcium alkaline series.The conclusion reflects that its source rock may be derived from the deep mantle.It is speculated that the Hamaling pluton is the same as the source rock of the Hamaling pluton.By comparison,the author believes that the mineralization conditions of the Mingshan pluton are similar to those of the Hamaling pluton.
