内蒙古科右前旗准艾勒扎拉格铅多金属矿矿床成因及找矿标志

Genesis and prospecting signs of Quasi Allezarag Pb polymetallic deposit in Horqin Right Front Banner, Inner Mongolia

推测该区矿床成因系由火山喷发时火山热液携带了成矿物质,在凝灰质角砾岩与凝灰岩中形成了矿(矿化)体。火山碎屑喷发同火山成矿热液同时上升(喷),经过搬运,在重力作用下聚集成矿。本区的找矿标志为含硫化矿物,含黄铁矿或偶见含方铅矿、闪锌矿及褐铁矿化的岩石及火山岩地区中酸性火山碎屑岩凝灰岩等。

It is speculated that the genesis of the deposit in this area is formed by volcanic hydrothermal fluid, which is the ore-forming material in the breccia and tuff of the limestone. Volcanic debris eruption and volcanic ore-forming hydrothermal rise（spray） at the same time, after handling, under the action of gravity to gather ore. The ore-prospecting signs in this area are sulfide-containing minerals, pyrite or occasional galena, sphalerite, and limonite-like rocks and limestone tuff in volcanic areas.
