冀东某地原生红刚玉矿床矿物学特征

河北省刚玉矿床（点）较多，但迄今还未发现宝石级工业矿床。冀东某地原生刚玉矿床具有埋藏浅、刚玉个体大、微红至暗红色、半透明至不透明等特点，经人工改善可生产低档红宝石。本文主要介绍该矿床的刚玉形态特征、物理性质、晶体结构、包裹体特征及矿床形成的地质条件，以期为该类矿产的开发利用提供部分基础性资料。

Mineralogy Property of Primary Corundum Deposit in the Somewhere of Hebei Province

Although there are many corundum deposits (spots) ,no industrial deposit of gem exists grade up to now in Hebei Province, which primary corundum ore has characteristic of shallow imbed, large grade, reddish - wine red color, translucence to opaque et al, but corundum can produce lower grade gems after manual improvement. The paper mainly introduces the shape character, physical property, crystalline structure and inclusion character and geological condition for forming ore, in order to offer some basic information for this kind of deposits.
