A geophysical investigation of the Roter Kamm impact crater, Namibia
Abstract The Roter Kamm impact crater is located in the southern Namib Desert. The crater has a diameter of 2.5 km and belongs to the category of simple, bowl‐shaped impact craters, with an elevated rim of fractured target rock. The crater's interior is completely buried beneath sediments, preventing extensive surface investigations of the bedrock ...

Bio‐mediated cementation of supratidal beach sediments associated with groundwater springs
ABSTRACT The formation of beachrock, sensu stricto, via carbonate precipitation in the intertidal zone is widespread throughout the tropics and subtropics. While cementation of supratidal beach sediments has also been noted in several locations, it has received much less attention.

Microbial mats in dinosaur ichnocoenoses
ABSTRACT Until now, the significance of microbial mats in preservation of dinosaur tracks and in reconstructing the palaeoenvironment in which dinosaurs roamed was rarely studied. Dinosaur tracks are commonly found close to ancient aquatic bodies where moist sediment had once allowed footstep registration.

ABSTRACT This research examines the spatial and geochemical interactions between mat‐forming microorganisms and thalassinid shrimp in an intertidal flat situated on the shores of Willapa Bay, Washington, USA. The study serves as a contemporary analog for the relationships between mats and burrowing organisms in deep time.

Abstract Studies of the Precambrian formations in the central Tafassasset area of the eastern Ahaggar mountains (Algeria) in the Sahara cast doubt on the existence of a Suggarian horst east of the great fault at 8 degrees 30'. The formations are difficult to distinguish from Pharusian formations to the north and south.

ABSTRACT Preserved allocyclic signatures in the rock record often reflect basin‐scale climatic variability and serve as key proxies for correlating ancient dryland successions. The notion of climate cyclicity, however, remains largely untested on regionally constrained, outcrop‐calibrated studies.
