黑龙江省阵巴尔虎旗“六一”硫铁矿是一个中型矿床。本文应用趋势面分析方法,结合矿床的具体特点,对矿体形态及其构造特征,作一初步讨论。一、矿床地质简介本区出露之岩石为中泥盆统火山岩,是以中酸—酸性为主的喷出岩。主要沿北东向构造带以裂隙式喷发形成。矿体产于片岩带中。该带介于酸性熔岩和中酸性凝灰熔岩之接触部位,由绢云片岩及绢云石英片岩等组成。矿区已知工业矿体有数个,V号矿体最大,Ⅰ、Ⅲ、Ⅶ、Ⅸ号矿体规模较小。矿体与围岩界线清楚,各矿体共生于同一矿带内,为挤压构造所控制。
Heilongjiang Province Barbaluqi “61” pyrite is a medium-sized deposit. In this paper, the trend surface analysis method, combined with the specific characteristics of the deposit, the ore body morphology and tectonic characteristics of a preliminary discussion. First, the geological description of the deposit The rock exposed in this area is the Middle Devonian volcanic rocks, is the acid - based acid-based expelled rock. Mainly along the north-east tectonic zone with fissure eruption formation. Ore bodies are produced in schist belts. The belt between the acidic lava and acidic limestone lava contact parts, by sericite schist and sericitite schist and other components. The mine is known to have several industrial ore bodies, the largest of which is the V ore body, and the smaller of the ore bodies of the Ⅰ, Ⅲ, Ⅶ, and Ⅸ. The line between the ore body and the surrounding rock is clear, and the ore bodies coexist in the same ore zone and controlled by the compression structure.
