Evolution Model for the Paleoproterozoic Talvivaara Mudstone‐Hosted Ni‐Zn‐Cu‐Co Deposit in Fennoscandia

Terra Nova, EarlyView.
ABSTRACT The Paleoproterozoic Talvivaara mudstone is a very large sulfidic Ni‐Co deposit that records enhanced organic matter accumulation during the global Shunga Event. Here, rock geochemistry and microscale S and Fe isotope composition of in situ pyrrhotites and pyrites are studied in well‐characterised, well‐preserved drill core samples.

Porosity Preservation in Deeply Buried (8500 m) Jurassic Calcareous Mudstones of the Vienna Basin (Austria)

Terra Nova, EarlyView.
ABSTRACT Significant porosity of more than 5% was found at depths of more than 8500 m in poorly sorted, calcareous mudstones of the Malmian Mikulov Formation. These overpressured rocks are the main hydrocarbon source rock in the Vienna Basin. Core samples from present‐day depths of 8150 m to 8550 m were analysed using X‐ray diffraction and scanning ...

Comparison of the Julian and Tuvalian beds in two cross-sections in the Central Sava Folds area (Slovenia)

Geologija, 2002
A lithostratigraphic subdivision of the Julian and Tuvalian beds in the Toško Čelo andVintarjevski potok area has been performed in this paper. The sedimentary sequence in the Toško Čelo area is subdivided into seven lithostratigraphic units, namely ...

Pengaruh Pemberian Dolomit terhadap Produktivitas dan Kualitas Rumput Raja dan Rumput Taiwan pada Tanah Latosol Ciampea-Bogor

, 2012
Providing of feed plays an important role on a farm and holds 60%-70% on production costs. Farmers take effort to provide feed for their farm, as example on Ciampea. Ciampea has acidic soil. That is called latosol soil.

Production of Dolomite Refractories

, 1953
Dolomite, unlike magnesite, is widely distributed throughout the earth’s crust. Both as a brick and a ramming mix, dolomite products are being utilized in large quantities in steel industries.

CO2 bubble formation on dolomite surface and its influence on surface wettability and flotation of dolomite

Dolomite is a common carbonate mineral that can release CO2 gas under acidic conditions. The formation of bubbles on the dolomite surface might play a critical role in the flotation separation of dolomite from apatite.

Modification of dolomitization on reservoir spaces in reef–shoal complex: A case study of Permian Changxing Formation, Sichuan Basin, SW China

Open Geosciences
The porosity of the reef–shoal complex increases with the increase of dolomite content, and it is worth investigating whether dolomitization leads to the formation of new pores or maintains the original porosity.
