阿尔及利亚Guettara锰矿地质特征及成矿模式探讨
Study on Geological Characteristics and Metallogenic Model of Guettara Manganese Deposits in Algeria
摘要
Abstract
The tectonic location of Guettara manganese deposit in Algeria is located in a faulted basin near three-node of the collision suture lines of three ancient plates(ATLAS,ANTI-ATLAS,SARLA)in northwest Africa.The overall direction is 300°along regional tectonic line.After geological exploration,10 manganese ore bodies have been discovered.They all occur in Neoproterozoic volcanic sedimentary stra-ta.The ore body is strictly controlled by stratigraphic position,and is roughly distributed in a monoclinic and parallel manner.It occurs in a layered-like,layered and lens like manner,and locally exposed on the surface.The ore body is distributed with the trend of NW—SE with a maximum extension of 475.00 m.The average grade of manganese deposit is 33.00%.It is a medium-sized manganese rich deposit with ex-cellent ore quality and easy mining.Based on geological characteristics of Guettara manganese deposit,combining with comprehensive study and analysis of ore controlling factors,mineralization models and other factors,it is believed that the origin of the deposit is a marine sedimentary metamorphic manganese deposit.The discovery of this deposit has certain reference significance for searching for similar deposits.关键词
