代写论文:海洋生物的形成

这些沉积物都安装到coarsening-upwards湖三角洲循环周期由罚款上限向上河流单位。海洋领域包括限制生物群中包含周期。Pittenween形成由泥和粉砂岩安排在coarsening-upwards三角洲周期有薄衬向上河流单位限制这些周期。多样化的生物群中丰富的地方形成薄海洋乐队。一小部分algal-rich油页岩中泥岩和粉砂岩·范·瓦格纳(1988)。粗化向上除了封顶的内心的河流三角洲周期单位形式沉积模式。海洋生物群是非常罕见的和罕见的海洋床存在通常是受限制的。Pathhead形成包括泥岩和粉砂岩与床的石灰石和白云石。此外,它还包含粗化向上侵蚀了薄,并向上罚款河流单位劳克斯。(2007)。粗化上升周期的石灰石、泥岩、砂岩和粉砂岩中重复低灰岩的形成。地球和煤床薄薄的座位帽这些周期。只是重复周期的砂岩、泥岩和粉砂岩灰岩中包括煤形成木匠,(1978)。上石灰石形成粗化上升周期的石灰岩回黑色泥岩、粉砂岩、砂岩和钙质泥岩。煤炭和稀土帽序列的座位。通道的形成也有细的粗粒度的交替结构粘土岩。

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.
