A. -Microfaciès / Microfacies

Géologie Méditerranéenne, 1979
On décrit les sédiments de la Mer Pélagienne en établissant les pourcentages des différents constituants, en particulier bioclastiques. Les sédiments sont essentiellement carbonatés avec peu d'éléments terrigènes, sauf près des côtes où il y a beaucoup de quartz et sous les eaux profondes (talus et fosses) où les argiles sont plus abondantes ...

SPWLA 61st Annual Online Symposium Transactions, 2020
Disclosed herein are methods and systems for analysis of a petrographic image of a sample of a subterranean formation, the method comprising performing an unsupervised machine-learning algorithm on the petrographic image, and determining a microfacies or a microfacies characteristic of the sample based on a segmented image provided by the unsupervised ...

Microfacies of Cambrian Limestones in Jordan

Facies, 1992
The limestones of the Wadi Nasb Formation of the uppermost Lower Cambrian of Jordan are under- and overlain by massive sandstones of a near-shore facies. Facies analysis is based on samples from an outcrop at the northeastern shore of the Dead Sea and two oil test wells in the Wadi Sirhan Depression in eastern Jordan.

Microfacies Interpretation: Summarizing Microfacies Criteria: Microfacies Types

2009
Microfacies studies aim for the recognition of overall patterns that reflect the history of carbonate rocks, by means of a thorough examination of their sedimentological and paleontological characteristics. The previous chapters have shown which thin-section criteria are used in describing the microfacies of limestones. The evaluation of microfacies in

Facies and microfacies of slope deposits

CATENA, 1999
Abstract This paper reviews the facies and microfacies of the main types of slope deposits. Lamination and sorting, when preserved, are good evidence for overland flow. Features due to deformation (folds, boudins, coatings and tails due to the rotation of clasts) are associated with the early stages of deformation in earth slides.
