Sideritic
Alkali basalt, basaltic andesite, and dacite occur at the bottom of the sequence, covered by a thick suite of variously-colored, marsh–lake facies sediments, including medium- to fine-grained sandstones, siltstones, conglomerates, argillites and coal, with sideritic ironstone layers (Li, 1998, Wu et al., 2007c).Stratification is defined by concentrations of mud-clast layers at the top of the sandstone sequence; (C) Beds of poorly and moderately sorted pebbly sandstone containing angular fragments of dark grey mudstone and sub-rounded brown sideritic clast. Some bioclastic fragments are also present; (D) Pebbly sandstone with large mud-clast and ...

The quarry cuts through a section of the Wealden group, specifically the Weald Clay. The clay was deposited in a lake and floodplain environment ...Siderite can therefore also contribute carbon during combustion of sideritic sediments and induce a significant bias for Rock-Eval analysis in such samples. This prevents the accurate measurement of MinC and TOC, while also leading to over- and underestimations of the OI and HI indices respectively.Synonyms for sideritic in Free Thesaurus. Antonyms for sideritic. 1 synonym for siderite: chalybite. What are synonyms for sideritic?Abstract. The generation of artifacts during sample preparation must be considered in paleobiological studies, particularly during the Ediacaran and Cambrian, since such artifacts can assume forms similar to those of cloudinids and other problematic taxa commonly described in samples from these systems. Chemical reactions between …The nodular limestone shows an internal network of radial cracks along the thick portion of the nodular band. These cracks are wide towards the center and the individual nodules resemble like septarian nodules. These cracks looks subsequently filled with sideritic carbonates (Fig. 3d). Moreover, this facies lacks any fossil component.5.08.3.11 Iron Carbonates. The most common iron carbonate is siderite (FeCO3 ), a frequent constituent of carbonate sediments and rocks on Earth. Siderite has a low-temperature transition at 30–35 K ( Housen et al., 1996 ), distinctively different from that of pyrrhotite ( Section 5.08.3.9 ). Siderite is paramagnetic at ordinary temperatures ... Siderite definition, a common mineral, iron carbonate, FeCO3, usually occurring in yellowish to deep-brown cleavable masses: a minor ore of iron.
