美国科罗拉多矿业大学论文代写:泥沙淤积

这些沉积物都形成了一个向上变粗的湖三角洲旋回,由上向上的河流单元所覆盖。海洋板块包括限制动物群中包含的周期。pittenween的形成是由泥和粉砂岩呈向上变粗的三角洲周期有薄衬上河流的单位盖这些周期。不同的动物群具有较丰富的地方形成薄的海洋带。一小部分藻类丰富的油页岩是包含在泥岩和siltstone Van Wagoner(1988)。粗隆向上的三角洲旋回,加上内生河流单元,形成沉积模式。海洋动物以及珍稀海洋床非常罕见的存在通常限制。Pathhead组包括泥岩和粉砂岩与石灰岩和白云岩层。此外,它还含有向上变粗erosively被薄,具有向上变细的河流单位Loucks铝。(2007)。灰岩、泥岩、砂岩和粉砂岩在下部灰岩地层中反复上升旋回。地面和煤块的薄层覆盖了这些周期的一些部分。石灰石煤系地层中仅重复了砂岩、泥岩和粉砂岩的循环,(1978)。石灰石上形成有向上变粗的循环灰覆盖的暗色泥岩、粉砂岩、砂岩、钙质泥岩。煤和阀座地球覆盖序列。通道的形成也有细到粗粒交替的结构系统。
石油系统概述
露头取样变得非常困难,以判断它们是否适合区域地层。它们之间存在的关系不称为序列。我们从Firth拍摄的现场取样和四。的kinkardine钻孔穿过东克拉克曼南向斜的东翼。两个正断层束缚了钻孔的位置。这些故障包括金卡丁渡轮故障和艾尔斯教堂故障。

These sediments are all fitted into a cycle of coarsening-upwards Lake Delta cycles which are capped by fining upward fluvial units. Marine segments including restricted faunas are contained in the cycles. Pittenween formation is made up of mud and siltstone which are arranged in coarsening-upwards deltaic cycles having thin lining upward fluvial units which caps these cycles. Diverse faunas which are abundant in places form thin marine bands. A small percentage of algal-rich oil shale is included in mudstone and siltstone Van Wagoner (1988). Coarsening upward deltaic cycles which are in addition capped by inner fluvial units forms the sedimentation pattern. Marine faunas are very rare along with rare marine beds are present are usually restricted. Pathhead formation includes mudstone and siltstone with beds of limestone and dolomite. Moreover, it also contains coarsening upwards erosively capped by thinner and has upward fining fluvial units Loucks at al. (2007). Coarsening upward cycles of limestone, mudstone, sandstone and siltstone are repeated in Lower Limestone Formation. Thin beds of seat earth and coals cap some of these cycles. Merely repeated cycles of sandstone, mudstone and siltstone are included in Limestone Coal Formation Carpenter, (1978). Upper lime stone formation has coarsening upward cycles of limestone overlain by dark mudstones, siltstone, sandstone and calcareous mudstone. Coal and seat earths cap the sequence. Passage formation also has fine to coarse grained which alternate the structure less claystones.
Petroleum System overview
It became extremely difficult to outcrop samples in order to judge that they whether fit into stratigraphy of area or not. The relationships existing between them are not known as sequence. We have taken field samples from both the Firth and Forth. The Kinkardine East borehole penetrates the eastern limb of the Clackmannan syncline. Large two normal faults bound the site of the borehole. These two faults include Kincardine Ferry Fault and the Airth Church fault.
