Initially, it may seem extremely daunting to be sitting in front of several thousand carats of
small diamonds, knowing that the likelihood of finding a diamond with a meaningful …

Unlike in the ocean basins where the shallow mantle eventually contributes to the
destruction of the overlying crust, the shallow mantle beneath continents serves as a stiff …

摘要华北岩石圈减薄是近十年来国内外研究的热门课题, 但关于岩石圈减薄的具体时间,
减薄幅度, 空间分布范围, 机制及其构造控制因素, 多有争论. 本文对上述问题进行了全面的回顾 …

The thermal thickness of Precambrian lithosphere is modeled and compared with estimates
from seismic tomography and xenolith data. We use the steady state thermal conductivity …

The global Archean record preserves ca. 35 large cratonic fragments and a less well defined
number of smaller slivers. Most Archean cratons display rifted margins of Proterozoic age …

How cratons—extremely stable continental areas of the Earth's crust—formed and remained
largely unchanged for more than 2,500 million years is much debated. Recent studies of …

The composition of the subcontinental lithospheric mantle (SCLM) varies in a systematic
way with the age of the last major tectonothermal event in the overlying crust. This secular …

The lithosphere–asthenosphere boundary (LAB) is a first-order structural discontinuity that
accommodates differential motion between tectonic plates and the underlying mantle …

Plate tectonic theory was developed 50 years ago and underpins most of our understanding
of Earth's evolution. The theory explains observations of magnetic lineations on the seafloor …

Geophysical data indicate that the lithosphere beneath the North China Craton (NCC) is∼
80 km thick with high heat flow within the craton. This is somewhat in disagreement with the …
