Microbially Induced Sedimentary Structures--A New Category Within the Classification of Primary Sedimentary Structures--Discussion

Microbially induced sedimentary structures in evaporite–siliciclastic sediments of Ras Gemsa sabkha, Red Sea Coast, Egypt

The coastal sabkha in Ras Gemsa, Red Sea coast with its colonizing microbial mats and biofilms was investigated. The sabkha sediments consist mainly of terrigenous siliciclastic material accompanied by the development of evaporites. Halite serves as a good conduit for light and reduces the effect of intensive harmful solar radiation, which allows microbial mats to survive and flourish. The micr...

Microbially Induced Sedimentary Structures as an Ecological Niche in Subtidal Early Triassic Environments of Eastern Panthalassa

investigating the feasibility of a proposed model for geometric design of deployable arch structures

deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...

Sedimentary structures and depositional environment of the Ashin Formation in Nakhlak area, Central Iran

Middle to Upper Triassic (Upper Ladinian to Lower Carnian) deep-sea sedimentary rocks crop out across a large area west of Nakhlak village, Central Iran and have been named Ashin Formation. The up to 304m thick, turbiditic, siliciclastic Ashin Formation consists of alternating turbiditic, thin- and medium-bedded calcareous sandstones, purple, fine-grained volcaniclastic sandstones, and mostly g...

Morphological Association of Microbially Induced Sedimentary Structures (miss) as a Paleoenvironmental Indicator: an Example from the Proterozoic Succession of the Southern North China Platform

The Ruyang (Mesoproterozoic; Pt2) and Luoyu (Neoproterozoic; Pt3) groups in the southern North China Platform are dominated by peritidal siliciclastic rocks and contain abundant microbially induced sedimentary structures (MISS), including multidirected and mat-protected ripple marks, mat chips, mat-smoothed ripple marks, various sand cracks, and irregular growth ridges. These MISS can be groupe...
