| 摘 要： | 绿泥石化蚀变岩带位于虎皮峪杂岩体北部。六块地－哈达岭一带，东西长８．２ｋｍ，产在辽河群里尔峪组磁铁矿浅粒岩段与电气石变粒岩段之间，由外向内可划分为４个蚀变亚带，其中绿泥石化、黄铁矿化亚带赋含铀矿。依据矿物蚀变关系、脉体切割关系，蚀变带内矿物生成顺序可划分３期６个阶段，铀矿化产于热液蚀变期。铀矿化受ＥＷ向绿泥石化蚀变岩带控制，与铀矿化有关的蚀变有绿泥石化、硅化、赤铁矿化，主要的合矿围岩有大理岩、蚀变浅粒岩。铀与铁、锰、钙、磷、铜、铅、镧、铈、钴呈正相关，而与造岩元素硅，铝，钾，钠呈负相关。铀矿物主要为沥青铀矿，形成于早元古代。揭露工作证明是一有远景的矿点。

| Abstract: | The chloritized alteration zone is located in the northern part of Hupiyu complex,between Liukuaidi and Hadaling. It is 8. 2 km long from east to west, 10-100m wide fromsouth to north,and occurs between magnetite-leptynite and tourmaline-fine grained granulite. From outer to inner part,it can be divided into four alteration subzones,of which uranium is hosted in the chloritized-pyritized alteration subzone. According to mineral alteration,veining dissection and formation sequence of minerals in the alteration zone,it can be dividedinto three periods and six stages. Uranium is formed during the hydrothermal alteration period. Uranium mineralization is controlled by EW-trending chloritized alteration zone and alterations associated with uranium include chloritization,silicification and hematitization. Mainuranium-hosting rocks are marble and altered leptynite. U is in positive correlation with Fe,Mn, Ca, P, Cu, Pb, La, Ce and Co, and in negative correlation with such rock forming elementsas Si,Al,K and Na. Uranium mineral is pitchblende which was formed in Lower Proterozoic.Exploration reveals that it is a prospective uranium occurrence. |
