MAIN ORE-CONTROLLING STRUCTURAL CHARACTERISTICS AND PROSPECTING MODEL OF MADAGASCAR GRAPHITE DEPOSIT

  • 摘要: 马达加斯加石墨矿床主要分布于马达加斯加岛中东部及南部,矿床类型丰富且成矿地质条件优越,具有良好的找矿前景。综合研究表明,石墨矿床成矿作用经历了自新太古代至新元古代沉积、变质变形及岩浆叠加改造三个阶段。控矿构造研究表明,中部石墨矿床主要受由于紧密同斜褶皱改造的变质片理构造控制,矿体翼部薄而转折端较厚。东部石墨矿床受同斜褶皱及顺变质片理的剪切带控制,并被后期沿脆性断裂迁移的热液叠加富集。南部石墨矿床由于受深层次剪切变形带的影响而延伸稳定。在控矿构造研究的基础上,提出针对石墨矿床"层带复合-岩浆叠加"为主体的区域找矿模型。结合已有矿化时空分布规律及成矿条件,提出了马达加斯加4个主要的成矿远景区。
