马朗凹陷哈尔加乌组火山岩相研究
|
摘要
根据岩心观察、岩石薄片鉴定、测井识别得出:马朗凹陷哈尔加乌组火山岩存在火山熔岩和火山碎屑岩两大类共23种具体岩石类型。岩性包括玄武岩类、安山岩类和部分中-基性过渡岩类,以玄武岩类为主。由单井相结合地震相分析得出,本区火山岩岩相存在5相8亚相类型,以喷溢相发育最为广泛。剖面上,火山岩相存在爆发-溢流-沉积、溢流-沉积、溢流-爆发-沉积三种相模式。平面相分析表明,爆发相沿主要断裂带呈串珠状分布,并且主要集中于近火山口附近,喷溢相呈沿爆发相外侧和沿裂隙两种形式广泛分布,火山沉积相主要分布在洼槽和火山机构之间的低洼地带。
By use of slice identification,core observation and logging identification,Haerjiawu formation volcanic in Malang sag is classified as lava and pyroclastic rock,concluding 23 kinds of specific rocks,such as basalt,andesite and part of intermediate-basic transition rocks,basalt is the main type.By combining logging and seismic,volcanic lithofacies can be divided into 5 categories and 8 subfacies.The result shows that effusive facies is the main lithofacies in the study area.In profile,volcanic lithofacies include 3 modes.The planephasing shows explosion facies is mainly concentrated in the vicinity of the crater,distributing as beads-strings along the dominating fracture.Excessive facies distributes in the lateral of explosion fasies and along the fracture,volcanic sedimentary facies mainly distributes between the subsags and low-lying area of volcanic institutions.
