Metamorphism and its bearing on geosystems

Geosystems and Geoenvironment, 2022
The Earth is a dynamic, ever-changing planet, and there exist many feedbacks and cycles that operate within and between its subsystems. Interactions between processes operating in the solid Earth, atmosphere, hydrosphere, and biosphere have become ...

Exposed weapons: A revised reconstruction of the facial anatomy and life appearance of the saber‐toothed cat Megantereon (Felidae, Machairodontinae)

The Anatomical Record, EarlyView.
Abstract Megantereon was a widespread saber‐toothed felid from the Pliocene and Pleistocene of the Old World and North America, but its rarity in the fossil record makes it complicated to restore its life appearance. Lack of complete specimens makes it necessary to combine information from fossils of different individuals to reconstruct their facial ...

Study on Fluid Inclusions and Genesis of Mengnuo Lead-zinc Deposit in Western Yunnan

Kuangchan zonghe liyong
The Mengnuo Pb-Zn deposit is a large Pb-Zn one in the Pb-Zn-Cu-Fe-Hg-Sb-As-Au metallogenic belt of Baoshan (block). There are different views on the genesis of the deposit, such as sedimentary-reworked type, exhalative sedimentary type (SEDEX) and ...

Subgrade geology beneath railways in Manchester [PDF]

, 2005
It is not sufficient to identify fine-grained soils, only, as locations for potential subgrade problems as could be done using a traditional 2D geological map.

Small fish, large variation: Morphological diversity of Weberian apparatus in Noturus catfishes and ecological implications

The Anatomical Record, EarlyView.
Abstract The Weberian apparatus is a hearing specialization unique to the otophysan fishes, and an unexpected degree of morphological variation exists in species of the Noturus catfishes. Our aim in this study is to investigate relationships between morphological variations and ecology that may drive this variation.

On the correlation of seismic intensity scales with the peaks of recorded strong ground motion [PDF]

, 1975
Correlations of the recorded peak acceleration, velocity and displacement, and the Modified Mercalli intensity have been carried out for 57 earthquakes and 187 strong-motion accelerograms recorded in the Western United States.

Is cranial anatomy indicative of fossoriality? A case study of the mammaliaform Hadrocodium wui

The Anatomical Record, EarlyView.
Abstract Determining the ecology of fossil species presents considerable challenges due to the often fragmentary preservation of specimens. The mammaliaform Hadrocodium wui from the Jurassic of China is known only from the cranium and mandible but may have had a fossorial lifestyle.
