, 1974 The origin of life is in a sense a genetic problem, for, as H. J. Muller pointed out many years ago, the essential attribute that identifies living matter is its capacity to replicate itself and its variants (1). Because this uniquely biological property

Combustion and Pyrolysis EA‐IRMS Techniques to Determine the δ2H of Diamonds
Rapid Communications in Mass Spectrometry, Volume 40, Issue 10, 30 May 2026.ABSTRACT Rationale Diamonds are generally considered to be metasomatic minerals originating from the Earth's mantle. They formed through the interaction of carbon‐bearing fluids or melts with the surrounding deep lithology. Most knowledge about the formation of diamonds comes from studying their mineral inclusions or stable isotopes.

Geophysical Research Letters, Volume 53, Issue 3, 16 February 2026.Abstract In this paper we document the first example‐the southern Delaware Basin‐where widespread induced triggered (as opposed to “driven”) seismicity across a large area exhibits a maximum magnitude truncation. The most likely cause of this truncation is that although the shallow faults in this area are many km in length, they are structurally ...

Геодинамика и тектонофизика, 2019 Eastern part of the Central Taimyr belt is composed of Precambrian rocks penetrated by granites of the Snezhnaya complex (845–825 million years) and later overlain by mid‐Neoproterozoic sin‐ postorogenic sedimentary deposits of the Stanovaya‐Kolosova ...

Late Triassic Hydroclimatic Changes in Central China Linked to Evolving Mountain Topography
Geophysical Research Letters, Volume 53, Issue 3, 16 February 2026.Abstract During the Late Triassic, tropical Pangea drifted northward into subtropical latitudes and became progressively drier. In contrast, South China, despite experiencing a similar latitudinal shift, transitioned from an arid to humid climate. Based on the sedimentary record of the Zigui Basin, this study constrains the arid to humid climatic shift

Geophysical Research Letters, Volume 53, Issue 3, 16 February 2026.Abstract The origin of a binary‐mixing of DM and EM1 sources for the Cenozoic intraplate volcanism in eastern Northeast China is yet unclear. Seismic attenuation imaging is a tool that can shed light on this question. Here we present the first map of teleseismic P‐wave attenuation across Northeast China.
