摘要
主要研究五大连池火山矿泥粒度组成及岩性定名,选取研究区域内30个矿泥样品,每个样品分上、中、下三层取样,利用英国MALVERN公司产的Master sizer2000型激光粒度仪测定每个样品平均值,探讨火山矿泥粒度组成情况;利用乌登——温特沃斯粒级标准,研究表明矿泥粒度主要由粉砂、细砂组成,还有部分黏土和中砂;利用谢帕德"黏土——粉砂——砂"三因分类法的三角图解,对五大连池火山矿泥进行岩性定名。
This paper mainly studies the Wudalianchi volcano mud named particle size and lithology. We selected 30 mud samples in the study area, and divide the sample into three layers, the upper layer, the middle layer and the bottom layer. The average value of each sample was determined by the sizer 2000 Master laser particle size analyzer produced by the British MALVERN company. This paper discusses the size composition of volcano mud. Udden- Wentworth grade standard was used in the research. Study shows that particle size is mainly composed of mud silt, fine sand and some part of clay and sand. Shepard＇s ＂clay-silt-sand＂ three triangular diagram classification method was used to name the lithology of Wudalianchi volcano mud.
