The Fennoscandian Shield represents a complex mosaic of Archean and Paleoproterozoic terranes that record successive cycles of rifting, accretion and collisional orogeny. Ancient crustal blocks formed ...

The University of Helsinki has educated four Nobel laureates and conferred an honorary doctorate on another one, Martti Ahtisaari. In addition, members of the University community have been awarded a ...

Chlorite alteration denotes the transformation of primary rock constituents into chlorite minerals under the influence of hydrothermal fluids or metamorphic overprint. This process occurs across a ...

HIGHLIGHTS: Tungsten mineralisation confirmed across entire 12km Glenburgh mineralised corridor within the mining lease. Elevated tungsten concentrations via routine ICP-MS analysis are observed ...

If you like the deepest and oldest mysteries, find a metamorphic rock. These rocks form deep within the Earth under extreme conditions. Take any rock, subject it to great heat, pressure, or chemical ...

Best results include 0.87% Sb over 12.5 m and 0.54% Sb over 17.0 m ...

There are three types of rock found on Earth. These are igneous, metamorphic and sedimentary. Each rock type is formed in a different way. For example, the rock malachite is mostly made of the ...

The rocks on Earth are constantly changing due to many different processes. There are three main types of rock, with rocks changing between each type over millions of years. This rock recycling is a ...

Abstract: Understanding geological differences in a proved reservoir requires precise facies classification. Predicting facies from seismic data is frequently seen as an inverse uncertainty ...

Abstract: As a classical visualization tool for seismic facies analysis, the clustering process of self-organizing map (SOM) is generally divided into two stages: feature extraction and clustering.

The recent interest in using deep learning for seismic interpretation tasks, such as facies classification, has been facing a significant obstacle, namely the absence of large publicly available ...

The ancient city of Napata at Jebel Barkal—home to pyramids, temples, and palaces and now a UNESCO World Heritage site—was a major urban center of the Nubian empire of Kush for over a millennium (1070 ...
