Crown Hill section of stratigraphic age discussion
Gan found in the lowest conodont zone of C ~ 3. FkixlaLeveni, compared with the region, under which there should be two fossil zone, indicating that there is still a below ground with an Wujiaping period. Jiangxi Xinyu Hill section of the Longtan officer found Schwagexlm molecular fossils, because of the limestone layer containing fossil remains controversial, the Jiangxi Lotus official Longtan West Yunshan Hill section of mine found NeomiselIina fossils. However, in the article pointed out various Thaipusam, which is different from Au tread Pingle Hill section of south-oriented government, the Southern-type depression to the south Pingle transitional type of transition. 2 and the underlying strata of the contact between the drill to expose the situation 2.1 years of work, in order to find out this problem, I collected a wide range of Pingxiang west, east Leping the exploration area within the drilling data of 126 . The contact between the type disclosed in more than 16 kinds. From the conglomerate and limestone (siliceous limestone) to carbonaceous shale and limestone and other types of contact have different sizes, which siltstone and (siliceous) limestone. Shale or clay and (siliceous) limestone contact with the majority. Followed by medium-grained sandstone and limestone, sandstone and limestone coarse type of contact. I Lin 1992 Yangqiao back Ida mine-resistant construction, see 1423 drillhole is: gray limestone interbedded thin gray calcareous siltstone (P1) and thin to medium thick-bedded dark gray siltstone (P2lt) contact, up and down dip line, the performance of integrated contact. 2.2 Surface trenching and survey the situation in the long-term field work, I trenching profile through the old field restoration, it was discovered Feng pit mining C152 trenching profile showing a mudstone (h) and siliceous limestone (Pl) contact, the contact surface under the same stratigraphic occurrence, for the integration of contact; and CAOO trenching profile of the situation is different, coarse sandstone (P2lI) and calcareous mudstone (P1) contact with the upper and lower strata like there are some differences. Performance of leisure unconformity; Yangqiao C148 measured stratigraphic section in northern mining,
mulberry outlet, shale (P) and siliceous limestone (PI) contact, the upper and lower strata like the same for the integration of contact. In the Yichun Hill section of the bottom of the long village official found conglomerate. The tendency to conglomerate with more than 100m wide in the along the track towards the 200m range, basically conglomerate based,
herve leger toronto, local phase becomes gravel or coarse sand coarse sand, gravel size from a few millimeters a few dozen centimeters, local See tens of centimeters of limestone blocks, sorting is poor. Second water chestnut-like, silicon argillaceous cement, level was 36 emerged a clear wavy bedding,
ed hardy uk, that particular point, I had 2 times to the site to observe, analyze, that the bottom of the conglomerates are sedimentary formation, rather than Tectonic, conformable contact between the two was false. These facts prove that, due to The overall effects were weak. By the time of the ancient geography of the region there are some differences, resulting in Crown Hill section and the underlying Maokou was integrated with the unconformity between the exposure to coexist. Early and late Permian boundary, it may be to the end of the official's Hill section of the appropriate. 3 Sequence comparison sequence is a relatively integrated, genetically related stratigraphic sequences, parasequences and systems from the domains. In a shallow non-marine strata. Parasequence is usually within the system and sequence the same domain. The Upper Permian in this area for a complete stratigraphic sequence. One old mountain sub-section, section equivalent to the low mountain system of the official domain, Laoshan rich Central Asia section of marine fossils, and there is marl or limestone, representing the maximum flooding surface. Lion Rock section, Wang Pan in segment highstand systems tract. The sequence of the Crown Hill section of the lower boundary with the formation Maokou contact surface, a sequence boundary is an unconformity and contrast integration. It is continuous in the horizontal surface of very widespread, at least over the surface of a full basin. Yichun Long Hill section of the bottom of the village official to flint limestone,
MBTシューズ 販売店, gravel-based discovery of basal conglomerate, on behalf of the unconformity or disconformity surface there, compared with the integration surface. Should be taken for granted Hill section of the district official with the underlying Maokou of the interface. Therefore, the stratigraphic sequence analysis, Permian upper and lower boundaries of the best optimal point system should be better in the bottom section of Crown Hill.
