新疆东北部三塘湖盆地马朗凹陷西山窑组层序地层格架及沉积相预测

综合应用岩芯、测井、三维地震等资料，对新疆东北部三塘湖盆地马朗凹陷西山窑组层序地层特征及沉积相进行系统研究。结果表明，西山窑组共识别出3个三级层序界面，将西山窑组分为2个三级层序（SQ1、SQ2），识别出4种主要的沉积体系：即辫状河三角洲、辫状河、冲积扇及湖泊沉积体系。在层序格架内，应用属性分析、频谱分解等技术对马朗凹陷主要勘探层系西山窑组SQ1层序低位域砂体的分布进行刻画，并以此为依据，进一步研究了马朗凹陷SQ1层序低位域沉积相的平面展布特征及演化规律，最终建立了该时期沉积发育模式，为油田的勘探开发提供了地质依据。

Discovery of Ignition Phenomenon of Early Cambrian Black Shale in Tianzhu County, Guizhou, China

The black shale of the bottom of Cambrian in Tianzhu County, Guizhou Province, China, has abundant carbon and muti-metal element. Ignition phenomenonof Cambrian black shale wasdiscovered by research group of barite deposit in Gongtang Village, Bandong Town, Tianzhu County, Guizhou Province, the ignition phenomenontook place at 7 year agofrom Gongtang Villagefarmer's introduction. Theignition of Cambrian black shale led to mountain with smog and strong sulphuric smell, and formed denthole, ash and sulphur.The ignition phenomenonof Early Cambrian black shale is first reported in the world, it is important to utilize muti-metal element in Cambrian black shale.
