查询词典 marl

A lot of brachiopod and mollusk fossils,including 12 species of 8 genera of brachiopod,14 species of 8 genera of bivalve and 5 species of 4 genera of gasteropod,are collected from the marl and mudstone situated on the bottom of Benxi Formation in Liujiang basin.The mollusk fossils are directly preserved in the upper part or facies change bed of brachiopod fossil bed.Up to now, the materials is firstly reported,especially the mollusk.

Hybrids of carbonate and terrigenous sediments Carbonate with terrigenous sediments are of characteristic from Emsian to Eifelian in stable shallow-sea faciesregion in Longmenshan area, and they can be classified evidently into hybrid Ⅰ and hybrid Ⅱ(Jingbaoshi-type). Type Ⅰ produced in mud shelf setting occupied hundreds of tempestite beds in which bottom cast、 hummocky cross bedding sandstones、 coquina were inter-beddded with shales that beared a great deal of verm traces、 bioturbations、 benthic communities dominative of brachiopods. Type Ⅱ in sand-mud-marl shelf was characterized by high-energy foreshore sandbeach facies and shelly bank facies.

碳酸盐与陆源碎屑混合沉积方面对微相、相特征、旋回样式、沉积机理研究表明，龙门山地区泥盆纪稳定浅海相区Emsian期和Eifelian期混合沉积十分发育，颇具特色，明显可以划分为两种类型：混积Ⅰ型，泥质陆棚背景下发育风暴沉积组构，幕式风暴期产生具丘状层理、底流冲刷构造的钙质砂岩、介壳岩，平息期则形成具大量虫管和生物扰动的深灰色、黄绿色页岩及海百合茎灰岩，腕足动物等大量繁盛；混积Ⅱ型，砂泥灰质陆棚背景下以发育高能前滨沙滩及生物介屑滩为特色，近滨至陆棚的砂泥灰互为混合，三者比例接近，肉眼难以区别确切岩石类型。

Most source rocks of the large marine oil-gas fields in domestic and overseas are graptolite shale, oil shale and marl with great amounts of clay mineral, which formed in the deepwater slope environment transferred from tableland to trough.But the carbonate rock is formed in the shallow water environment under good exchanging condition with atmosphere, which causes the low abundance of organic matter and poor-type kerogen.

国内外海相大油气田的烃源岩多为黏土矿物含量较高的泥页岩、油页岩和泥灰岩，形成于由台地向海槽过渡的深水斜坡环境，而碳酸盐岩形成于与大气交换条件较好的浅水环境，是有机质丰度低和干酪根类型差的根本原因。
