摘要 

内蒙古准苏吉花斑岩型钼矿床是一个中型金属矿床,目前勘查区内还没有较深的钻孔资料。为探测深部隐伏金属矿和控矿构造及深部地质结构,在内蒙古准苏吉花钼矿区及其外围开展了高精度反射地震测量。该反射地震采用2台套大功率可控震源激发,5 m道间距,960道接收,80次覆盖的工作方法,获得了能清晰反映深部地质结构和构造的高精度反射地震剖面。在该剖面上,能够清楚地解释测区导矿和控矿构造及隐伏岩体分布及燕山期与华力西期岩体的交切关系,并据此讨论了地壳深部流体运移的路径和动力过程,为在该区寻找深部隐伏金属矿指明了新的找矿靶区。

Abstract

The Zhunsujihua porphyry molybdenum deposit of Inner Mongolia is a medium sized metal deposits.Currently there is no deep drill hole data within the exploration area.In this study, high-precision seismic reflection measurement was conducted for detecting the deep metal deposits, ore-controlling structure and deep geological structure in the molybdenum ore district and its periphery.The reflection seismic method of 2 sets of high power vibrator for stimulation, 5 m group interval, 960 receiving and 80 folds were used, and high-precision seismic reflection profiles which can reflect clearly deep geological structure was obtained.Ore-passage structure and ore-controlling structure, concealed rock mass distribution as well as cross-cutting relationships of rock masses of Variscan and Yanshan period can be clearly explained on the section.The deep crustal fluid migration paths and dynamic process are discussed.The prospecting target zone is delineated in search for concealed metal ore deposits in the area.
