Article13 January 2020 Introduction For over a century, the classical paradigm of magma chambers has underpinned all models of the Earth’s magmatism. This paradigm envisages a magma chamber as a large body of the molten, long-lived, and slowly fractionating magma (‘a big magma tank’) enclo...
In this paper we focus on a thermal origin for the layer and conduct a systematic study on the thermal evolution of the core. We develop a new numerical code to model the growth of thermally stable layers beneath the CMB, integrated into a thermodynamic model for the long term evolution of...
The influences of composition, texture and diagenesis on reservoir quality were also discussed in this article. Diagenesis of the Chang 7 tight oil reservoirs was mainly composed of mechanical compaction, grain dissolution and cementation by quartz, carbonates and various clay minerals. Reduction of ...
全球地表水覆盖(Global Surface Water)是利用1984至2019年获取的landsat5、landsat7和landsat8的卫星影像,生成分辨率为30米的一套全球地表水覆盖的地图集。用户可以在全球尺度上按地区回溯某个时间上地表水分的变化情况。该数据集包含 change为全球地表水体变化程度,它提供了1984-1999年和2000-2019年间地表水发生增加、...
Aquatic surface microlayers are unique microbial ecosystems found at the air–water interface of all open water bodies and are often referred to as the neuston. Unambiguous interpretation of the microbiology of aquatic surface microlayers relies on robust sampling, for which several methods are availa...

Article Open access 14 September 2020 Introduction The extent, duration, and magnitude of annual surface melting significantly affect the mass balance of the Greenland Ice Sheet. Roughly 55% of Greenland’s mass loss since 2000 is attributed to decreasing surface mass balance (SMB) driven by incr...
