Zhuyin: bo shi
Denudation interpretation
Meaning: (1) The surface of the material is damaged by weathering: because of the weather, the words in the stone carvings are hard to recognize. (2) Wind, running water, glaciers, etc. destroy the earth's surface and gradually flatten the uplifted part. (3) erosion.
Denudation sentence making
1 Russia is more resistant than its former satellite countries, but the erosion of manufacturing competitiveness is covered by soaring oil and gas prices.
2. For example, if you want to photograph a country house in the Woods, the ideal material is a primitive building that has been eroded by wind and rain, not a house with plastic siding.
3. These zircons were denuded from older rocks and then entered the rocks of Jack Hill. The researchers made great efforts to sort out these zircon crystals from other mineral fragments.
4. The main and eastern ore deposits have experienced strong weathering and denudation since Cenozoic, and there are alluvial enrichment phenomena.
5. The wind and rain have eroded it, the lightning has bombarded it, and the war has passed through it. The big tree to which it is attached has grown and grown tall, until it collapsed one night.
6. In Africa, Asia and Latin America, soil erosion is very serious due to the disappearance of forest vegetation, over-exploitation of cultivated land and over-grazing of pasture.
7. If the volcano becomes inactive and cools down, the surrounding rock may be eroded away.
8. This kiosk is on display at the Hong Kong International Art Exhibition recently. Patzold looked at its weathered surface and showed me layers of paint: yellow primer, a layer of tender green and the topmost dark green.
9. The fault was formed in the middle Archean and began to control the deposition and erosion on both sides.
10, lateritic gold deposits in Zima and Yangchang areas were formed by weathering, denudation and accumulation of gold-bearing layers in Longtan Formation of Upper Permian.
1 1, and the moderate erosion degree in this area is conducive to finding deposits in the volcanic root zone or basement.
12, Chengdao area has experienced multi-stage tectonic movement and multi-stage fracture and denudation, which has created favorable conditions for oil and gas accumulation.
13. This difference reflects the denudation of different rocks in Nyainqentanglha Mountain during the uplift of the Qinghai-Tibet Plateau.
14, erosion gives it a honeycomb shape.
15. Through geological analysis and practice, the stratum denudation amount in the study area is calculated by using the trend extension method of stratum structure and acoustic logging curve method, and on this basis, the prototype basin is restored.
16, at the same time, the influence of tectonic uplift, denudation and chemical weathering on the determination of provenance should also be considered.
17, and based on the thickness data, it can estimate the thickness of stratum denudation in almost all cases, and has wide adaptability.
18, therefore, the denuded area is not a reflection of uplift structure, and it has no effect on controlling oil and gas distribution.
19. In the fault zone and the uplift area at the outer edge, the stratum denudation degree is great, and it is difficult to determine the active time.
20. The strong denudation in the later period destroyed the early primary oil and gas reservoirs, and at the same time led to the formation of shallow secondary oil and gas reservoirs.
2 1, with such an environment, the degree of weathering and erosion of ore bodies is greatly reduced.
22. The degree of stratum denudation and fault activity are the key factors for oil and gas preservation.
23. Controlled by sedimentary erosion and basin tectonic-thermal evolution, the hydrocarbon generation stages and processes of source rock series have the characteristics of multi-stages.
24. The results of field geological and geomorphological investigation and DEM analysis of the western Sichuan Plateau show that there are two levels of planation plane and one level of denudation plane in the western Sichuan Plateau.
25. Wind and rain eroded the soil on the hillside.
26. The difference of laterization degree of weathering crust on the denudation surface in front of the mountain at different altitudes is the product of weathering in different periods.
27. Therefore, it is likely that the uplift, denudation and pressure relief of the earth's crust will lead to the rebound of sand bodies and pump oil and gas to form reservoirs.
28. According to the relationship between vitrinite reflectivity and depth, the denudation thickness of different structural units is restored.
