carbonite

This formation is dominated by a set of sandstone - mudstone dark clastic rock series which belongs to marginal marine deposit at the end of the gondwana carboniferous - permian glacier period 該組主要為一套砂巖泥巖的暗色碎屑巖系,屬岡瓦納石炭二疊紀冰川末期的邊緣海沉積。

From the late carboniferous to the end of permian , the spores of the shishuyuan trough were from the north china province , and the marine sediments were absent in the southern part of eqm 晚石炭世至二疊紀末,柿樹園海槽的孢子見于華北生物省,東秦嶺南部缺乏海相沉積。

Started from benxi stage of late carboniferous , deposits of epiric sea were developed in this area along with the spreading of west - east direction and gentle depression of the basement 從晚石炭世本溪期開始,由于東西向拉張,基底緩慢下沉,本區廣泛發育陸表海沉積。

With rapid burial in a moist anoxic environment , such as the coal swamps of the carboniferous period , carbonaceaous films of plant material like fern fronds may survive 迅速埋藏于潮濕的缺氧環境下,正如媒在石炭紀沉沒,類似蕨類植物的含碳植物材料即可能存活下來。

They were marine basins before carboniferous , and evolved into continental basins after triassic by transformation from the marine facies into the continental facies in permian 同樣,在儲集條件方面,中國類前陸盆地除發育海相儲集層外,還廣泛分布陸相儲集層。

The region was subsequently inundated by a shallow sea . sediments laid down during this time are represented by the carboniferous marble of yuen long and ma on shan 該地區其后遭淺海淹沒,期間沉積物不斷積聚,元朗和馬鞍山的石炭紀大理巖,便是該時期的產物。

The increasing volcanism implies that the regional tectonism became progressively severe from the early stage to late stage of the late carboniferous 自晚石炭世早期到晚期,火山活動期逐漸增長,休眠期逐漸縮短,反映出盆地性質自穩定向活動的轉化過程。

The key metallogenic stage is late carboniferous - early permian , mahuanggou - matoutan , qishitan and shiyingtan are the main prospect regions for gold metallogenesis and prospecting 麻黃溝馬頭灘、齊石灘、石英灘等地段是本區重要成礦和找礦遠景地段。

With sequence as drawing unit , the distribution and evolution of sedimentary facies are described and explicated in six sequences about carboniferous in the region 以層序為作圖單位,勾劃并闡明本區石炭系六個層序的沉積相展布以及沉積演化規律。

There are well source - reservoir - cap rock assemblages and suitable petroleum pool - forming conditions in carboniferous strata 根據石炭系石油地質條件分析,劃分出巴彥浩特盆地、河西走廊東部、河西走廊西部等3個評價區塊。

Geochemical characteristics and paleogeographic significance of early carboniferous cherts at the nongba section in the gengma area , southwestern yunnan 滇西南耿馬地區弄巴剖面早石炭世硅質巖的地球化學特征及古地理意義

The two early carboniferous fragments are composed of basalt and ash - black , fuchsia radiolaria silicalite , siliceous mudstone , tuff 早石炭世兩個斷片由玄武巖和灰白色、紫紅色放射蟲硅質巖、硅質泥巖、凝灰巖組成。

In the burren there is a region of bare carboniferous limestone containing arctic - alpine plants which survived from the last glaciation Burren有一個只有石碳紀石灰石的地區,那里有從上個冰期生活下來的北極高山植物。

Coal , carbargilite in permo - carboniferous and carbonate in ordovician system were the main source rock of natural gas in the researched area 石炭二疊系分布的煤層、炭質泥巖和奧陶系碳酸鹽巖是研究區主要的氣源巖。

Analysis on lithofacies and paleogeography coal accumulation for coal measures of the carboniferous - permian period in the east of shan - mian coalfield , henan 豫西陜澠煤田東部石炭二疊紀含煤巖系巖相古地理分析
