山东泗水董庄石膏矿矿床地质特征及成因分析
|
摘要
董庄石膏矿位于泗水盆地中,区内古近纪地层发育,卞桥组发育较齐全,其中卞桥组二段为含膏岩系。盆地内含膏层岩石组合为巨砾岩、砂砾岩、砂质黏土、黏土岩及含膏层。共有含膏层9层,含膏层与其他岩层呈过渡关系,没有一定的规律,含矿带产状变化不大。矿层中含矿率低(15%左右),矿石类型以石膏为主,可分为原生石膏和次生石膏。董庄矿床沉积于内陆泻湖盆地,在沉积过程中由于盆地中水量的不断蒸发,CaSO4浓度的不断增加,同时黏土类物质的不断沉积,形成了本区的主要矿床类型—以黏土岩为主含石膏的矿床。对石膏矿地质特征、矿石质量及矿床成因进行了分析研究,可为泗水盆地内石膏矿的找矿勘查提供参考和借鉴。
Dongzhuang Gypsum Mine locates in the Sishui basin,it develops Paleogene system,and develops fully equipped with Bianqiao group,which is the second paragraph Bianqiao group for gypsum rock series. The rock assemblage of containing paste layer rock assemblage is glutenite、sandy clay and contain paste layer. It has nine cream containing layers and the relationship between the paste layer and other layers is show transition,it has no belt occurrence. The including ore seam in the mineral content is low( 15%),the main ore type is gypsum,and can be divided into native gypsum and gypsum. The Dongzhuang deposit sedimented in the inland lagoon basin,as in the process of sedimentary,the water evaporating and CaSO4 concentration increasing,at the same time,the sedimentary clay class sedimenting,formed the clay rock gypsiferous deposits,which is the main ore deposit. This paper analyzes and researches the geological characteristics,ore quality and ore deposit genesis of the gypsum mine,and can provides reference and reference in the gypsum mine prospecting exploration.
