Carbonate sedimentology: An evolved discipline

The Depositional Record, EarlyView.
Abstract Although admired and examined since antiquity, carbonate sediment and rock research really began with Charles Darwin who, during a discovery phase, studied, documented and interpreted their nature in the mid‐19th century. The modern discipline, however, really began after World War II and evolved in two distinct phases.

Deciphering depositional controls and evolution of a lacustrine supradetachment basin through facies analysis: Gördes Basin, Western Türkiye

The Depositional Record, EarlyView.
The lacustrine Gördes Supradetachment Basin was developed along the Simav detachment fault during postorogenic extension in the north of the Menderes Massif in western Anatolia. The basin‐fill succession is represented by alluvial fan, Gilbert‐type delta, shoal‐water delta, foreshore, shoreface, offshore‐transition and peat‐forming mire deposits.

Laguna Fuente de Piedra: An example of a dolomite factory recording ~50,000 years of depositional and paleoclimatic evolution

The Depositional Record, EarlyView.
This study characterises carbonate mineral precipitation mechanisms and their paleoenvironmental implications in a semi‐arid, saline playa lake system. SEM image with EDS spectra shows microcrystalline, spherical shaped dolomite crystals from Laguna Fuente de Piedra composed of nanocrystals with bacterial voids and EPS.

Controlling factors and evolution of reservoirs in continental rift lacustrine carbonate factory: insight from the cretaceous ITP-BVE formation in Brazil’s Santos Basin

Frontiers in Earth Science
The Cretaceous Itapema and Barra Velha Formations in Brazil’s Santos Basin represent a rare giant rift lacustrine carbonate factory with considerable potential for oil and gas exploration.

Precipitation mechanism of anhydrite cement in lacustrine tight sandstone: Implications for fluid activity, mass transfer and pore origin of open diagenetic system in tight sandstone

The Depositional Record, EarlyView.
This paper discusses a new model concerning the precipitation mechanismand significance of anhydrite cement in tight sandstone. Anhydrite cement ismainly formed by the dissolution and reprecipitation of early‐diageneticcalcite cements, feldspars and volcanic rock fragments at the mesodiageneticstage.

Optimal mud pressure design using nonlinear failure criteria for wellbores in shaley sedimentary reservoir

Deep Underground Science and Engineering, EarlyView.
The present study uses the Modified Mohr‐Coulomb true‐triaxial failure criterion (MMC_TT), which predicts the strength of rock better than the MGC criterion in laboratory true‐triaxial tests to overcome the limitations. Moreover, based on the data from previously published five vertical wells in the Krishna‐Godavari basin (K‐G basin), an empirical ...

Nuttalliellidae in Burmese amber: implications for tick evolution

Parasitology
Ticks are composed of 3 extant families (Argasidae, Ixodidae and Nuttalliellidae) and 2 extinct families (Deinocrotonidae and Khimairidae). The Nuttalliellidae possess one extant species (Nuttalliella namaqua) limited to the Afrotropic region.
