The conglomerate lithofacies generally overlies sharp irregular contacts ( Figure 3 B, D). The sandstone lithofacies commonly overlies the conglomerates and underlies the mudstone...

Three lithofacies are emphasized in the study: (1) the conglomerate-sandstone; (2) the volcanic; and (3) the pyroclastic lithofacies. The 2–40 m thick conglomerate-... ... 2 -40 m thick...

According to particle size, bedding, and genetic characteristics, it can be further subdivided into six types of lithofacies: grain-supported, massive pebbly sandstone (S1); grain-supported,...

Diagram showing general terminology (proximal Vs. distal facies) on an alluvial fan. a. Proximal settings: i.) Texturally immature, very coarse-grained, angular-subrounded clasts. ii.) Conglomerates, matrix supported clasts-supported fabrics. iii.) Unstable minerals present [f (source rock)] = compositionally immature (usually) iv.)

Displaying lithofacies data is commonly done by using either a sedimentary log/vertical profile or a section diagram. Sedimentary logs or vertical profiles (measured or composite) are a quick and relatively simple visual method for summarizing the vertical distribution of lithofacies and are particularly suitable for compilation in the field ...

Creating a Lithofacies Map. One of the most important tools for reconstructing ancient environments is a lithofacies map – a map showing the distribution of rock types (lithofacies) in an area. If the rocks are the same age, this map records the relative positions of various environmental settings at that time in the past.

Conglomerate: The specimen shown is about two inches (five centimeters) across. It is made up of chert and limestone clasts bound in a matrix of sand- and clay-size particles. What is Conglomerate? Conglomerate is a clastic sedimentary rock made up of rounded clasts that are greater than two millimeters in diameter.

2016年4月6日 · Lithofacies maps show the areal variation in the depositional patterns that make up each genetic sequence within the reservoir interval. The method for constructing lithofacies maps involves extrapolating the lithofacies from the wells into the gaps between the wells.

2023年6月1日 · These facies were divided into conglomerate (Gcs, Gms, Gsp, and Gbp) and sandy lithofacies (Sm, Sh, Sp, and Sr). The coarsest sequence, mainly comprising conglomerates, represents deposition in a proximal alluvial fan.
