剥蚀

Being controlled by the rheology of the lower crust, erosion may level off the topography, and can break the balance of kinetics and thermodynamics inside of the crust therefore rebuild the structure and component of the curst. the uplift process of the mountains is then enhanced; we believe that the rate of the exhumation is controlled by both the uplift of orogen and the outer spheres of the earth.

在下地壳物质层流变作用机制的调节下，地表剥蚀作用并不仅仅是传统意义上地表夷平的因素，它还能打破地壳动力学和热力学平衡，引起地壳内物质和结构的重置，进而促成山脉的加剧隆升；地表剥蚀作用的强度既受控于造山带的抬升，也受制于地球外圈层。

The theoretical estimation formulas for denudation time and denudation rate of the young geology body were established.

在此基础上，对整个剥蚀区不同位置剥蚀速率进行了分析。

The trend of denudation was analyzed. The tectonic framework of Tazhong area presented as"west-east differentiation and north-south dissimilitude". Based on the seismic profile, the major pattern of the faults was thrust fault with high angles and involved in base, and the main thrust faults developed back to back companion faults, which formed flower structure.

在精细解释塔中地震剖面的基础上，主要利用地质结构外延法，估算了塔中隆起的三个主要不整合面-中泥盆的顶面、早奥陶的顶面和晚奥陶的顶面的地层剥蚀量，并分析了剥蚀量趋势。

Exhibiting angle unconformities or erosion unconformities in different part of the basin, these surfaces are obvious to be recognized on seismic profiles.T1 conformity, separating Eogene from Neogene, was formed during the whole basin uplifting and erosion by the end of Eogene.T1 unconformity denuded unbearing strata differently, and the deeper and thickest erosion lies on the southern margin of the basin, which reflects the activity of southern Jiangnan paleo-terrene. In conclusion, the major erosion belts extending along NW direction reflects NE-SW compression and slipping caused the Eogene basin uplift and strengthen the earlier NW direction extending low convex, and formed the NW direction extending depress and erosion belts.

古近系和新近系之间的T1不整合面形成于古近纪末期的盆地整体抬升，对下伏地层造成不同程度的剥蚀，沿盆地南缘的剥蚀层位深，剥蚀量大，反映盆地南缘整体相对隆起，与江南古陆的隆起作用有关。T1界面剥蚀带走向以北西向为主，反映了盆地在古近纪末受到了北东－南西向的挤压或压扭作用，该作用造成盆地整体抬升，强化了北西向展布的低凸起，产生了近北西向的洼陷和剥蚀带。

Considering principles of sedimentation geology, utilizing the premise that two sequential layers (eroded and underneath uneroded layers) enjoy approximate deposition speeds, we plot with residual thickness values and thickness values of underneath uneroded layer in cross sections. By analyzing the diagram, we can not only obtain the eroded thickness of strata, but also explain the original sedimental environment of the eroded strata and the later structural erosion causes.

介绍了4种解释模型，充分考虑了沉积地质学原理，利用相邻两层沉积速率相近这个前提条件，通过在纵剖面上对剥蚀层残余厚度及下伏未剥蚀层厚度值进行坐标投点，分析它们的图形分布规律，不仅可以量化求取剥蚀厚度值，还可以对剥蚀层的原始沉积环境及造成剥蚀的后期改造作用，做出重要的地质成因解释。

The analysis of weathering crust characteristic of lower Permian Kalagang group in Malang sag, Santanghu basin suggests that the paleo-weathered crust includes weathering clay ground, strong weathering rubble layer, weak, weathering block-stone layer and unweathered rock layer in vertical and was distributed under the unconformity interface and presented in planar manner horizontally.

对三塘湖盆地马朗凹陷下二叠统卡拉岗组风化壳特征的分析，认为古风化壳纵向上分为风化粘土层、强风化碎石层、弱风化块石层以及未风化岩石层等，平面上呈面状分布于不整合界面之下，剖析该区古风化壳成藏地质条件和构造演化，探讨了可能发育油气藏类型及与风化壳的关系，并指出了该区下一步下二叠统卡拉岗组有利的勘探目标是在P2t剥蚀线与P1k剥蚀线之间范围内，其次为卡拉岗组剥蚀线以东地区。

The denuded thickness of different locations in...

通过分析可以更准确地估算出整个剥蚀区不同位置的剥蚀厚度，从而可恢复剥蚀面的古地貌。

Two episodes of uplifting in Jianghan basin occurred within 157～97Ma and 10~0 Ma; Xiang′exi-Wuling region and Qianzhong hights experienced an uplifting of 137~0 Ma; Exiyudong, Chuandong folds and Chuandongnan regions, 97~0 Ma; Chuandongbei and Chuanzhong regions, 56~0 Ma; Chuanxi and Dianxi areas 23~0 Ma. The general trend is that the onsets of uplifting for different tectonic units in the Mid-upper Yangtze area decrease westward.

江汉盆地在157～97Ma和10 Ma以来发生了两期大规模抬升剥蚀；湘鄂西—武陵地区、黔中隆起自137Ma开始持续抬升剥蚀；鄂西渝东、川东褶皱带从97 Ma开始持续抬升剥蚀；川东北和川中地区于56 Ma才开始遭受抬升剥蚀；川西—滇西地区则自23 Ma以来经历了较大规模的抬升剥蚀。

In practical study, the essential flow is""on the basis of the study of the faults, strata denuded thickness and original thickness, analyzing the controlling effect of the faults to the sedimentation and denudation, and combined with the areal geology background, reconstructing the basin prototype of each stage"". 2. As the basic theories and methods of the calculation of the denuded thickness, such as, the methods of cosmogenic nuclides, wave equation, apatite fission track, structural sections, acoustic wave, vitrinite reflection, etc, were argued detailedly , and their applicable ranges were analyzed , the denuded strata thickness of each structural layer layer of pre-Tertiary was reconstructed.

In the United States, chronic alcoholism and hepatitis C are the most common ones.

在美国，慢性酒精中毒，肝炎是最常见的。
