文章论述了茗岭瓷土矿的地质特征,并对其成矿地质条件进行了研究,认为该矿床的形成主岩浆岩、构造、地形地貌及气候植被等诸因素的制约。
As a result of the research on the geology of Mingling porcelain clay deposit.this pa- per describes its geological characteristics and geological mineralization conditions,considering the igneous rock,structure,landform,climate and vegetation are very important to the mine- ralization of deposit.The igneous rocks consist of quartz monzonite porphyry,quartz、and porphyry-like granite.The porcelain clay mainly produced in the contact belt of altered aci- dic complex and sandstone of Maoshan Group,is composed of altered rock which has been altered through wheatering and infiltration.The deposit belongs to eluvial deposit type. The Mingling porcelain clay deposit is considered as a typical eluvial nonmetal deposit formed by wheathering and infiltration in the area.Its forming conditions is also considered as wheathering and infiltration on the igneous rock.In the autometamorphism stage,feldspar has been kaolinized and Al_2O_3 accumulated,which are the basis of the mineralization.In the wheathering and infiltration stage,Si,K,Na,Ca and Mg etc.elements in the rock has been eliminated and Al_2O_3 further accumulated in the rock.The above two activities acting on the igneous rock constitutes the main mineralization of Mingling porcelain clay deposit. The chemical composition of Mingling porcelain clay has met the needs of ceramic industrial standards even though its quality is not very good.The crude clay separated wi- th hands has reached (?)30-60/t.The deposit is characterized by shallow burried,simple minig techniques and convinient transportation.It is very suitable for township enterp- rises.
