矿石自然类型

焙烧高岭土、火烧角砾岩、火烧岩、烧变泥岩四种矿石自然类型。

Its natural types are roasted kaolin , burnt breccia , burnt rock and burnt mudstone .

矿石自然类型以块状、网脉状块状石膏为主，其次为网脉状浸染状石膏、硬石膏和纤维状石膏。

Mass , net vein-mass gypsum are its major types , also has some net vein disseminated gypsum , anhydrite and filament gypsum .

矿石自然类型有碎屑状铝土矿、粗糙状铝土矿、豆鲕状铝土矿、致密状铝土矿，其中粗糙状铝土矿石品味最高，豆鲕、碎屑状铝土矿石次之，致密状铝土矿石最差。

Natural types of ores are clastic bauxite bauxite , rough shape , bean oolitic bauxite , dense type bauxite . The rough shape of bauxite tastes highest , beans oolitic and clastic bauxite followed by , dense type bauxite worst .

从矿石结构、构造、矿体产状、矿石自然类型的分布规律及地球化学特征等方面分析，火山成矿作用是该矿床形成的重要因素。

Volcanic ore-forming process proved to be the major factor in the formation of the deposit after analyses were made on the ore textures and structures , orebody occurrences , distribution law of the natural types of ores and geochemistry .

首先按风化程度、矿石组分结构构造不同特点，将磷块岩划分为十种矿石自然类型。

The phosphorite in the study area was first divided into ten main ore types affiliated to two groups of primary and weathered phosphorite .
