摘要:

宁阳县黑山头饰面用变粒角闪岩矿床赋存在阜平期蒙山超单元龟蒙顶单元片麻状中粒含黑云花岗闪长岩和西官庄单元片麻状中粒含黑云角闪英云闪长岩中。矿体为新太古代五台期麻塔单元粗粒变角闪石岩，墨绿色，夹杂白色较大不规则条带，中粗粒变晶结构，块状构造。区内主要有1个矿体，呈岩脉状产出，倾角西陡东缓，矿体中间薄两端厚，连续性较好，属于岩浆型花岗岩矿床。

Abstract:

Decorative amphibolite deposit in Heishantou of Ningyang country occurred in gneissic medium grained biotitic granodiorite of Guimeng unit in Mengshan superunit in Fuping period and gneissic mediumgrained biotitic amphibolitic tonalite in Xiguanzhuang unit. Ore bodies are coarse grained metahornblendite in Neoarchean Wutai period. They are black green with white large irregular stripe, belonging to medium coarse grained crystalloblastic texture and massive structure. There is mainly one ore body and occur with vein type. Its dip angle is gentle slope in the east and steep slope in the west. It belongs to magmatic granite deposit.
