(一) 矿床的地質概況 河北省武安——涉县一带的矽卡岩型铁矿是分佈在太行山东麓中段,武安盆地边缘、山西台背斜与河淮台向斜的过渡地带。矿体大体上与主要构造綫相吻合,呈南北向分佈,多半沿燕山期中性火成岩侵入体接触带的凸出或凹入的部份而生成,接触的成矿因岩为中奧陶紀馬家沟灰岩,与成矿有关的火成岩大部为石英閃长岩或二长岩,如图1。
(I) Geological Profile of Deposits Skarn type iron mines in Wuxian-Shexian area of Hebei Province are transitional zones distributed in the middle part of the foot of the Taihang Mountains, the margin of the Wu’an Basin, the synclines of the Taiwan Anticline and the Huanghuai Taiwan. The ore body generally coincides with the main tectonic line and is distributed in a north-south direction. Most of the ore body is formed along the bulge or indented part of the contact zone of the neutral igneous rocks in the Yanshanian period. Jiagou limestone, most of the igneous rocks related to metallogenetic formation are quartz diorite or monzonite, as shown in Fig.1.
