Tufa is a type of limestone made of microscopic layers of microcrystalline calcite. Whereas marl often contains microscopic fossils of algae, diatoms, and ostracods, tufa may contain algae and larger fossils including, leaves ...These sediments are interrupted by local buildups of lime mudstone, skeletal wackestone, packstone, and grainstone. The buildups range in height from 30 to 100 m above the starved-basin sediments. Those in southeast Saskatchewan are between approximately 30 …Common rock types in Oal are dolomitic, locally argillaceous lime mudstone and grainstone made up mainly of peloids and intraclasts with lesser bioclasts and ooids. Mud-supported strata are bioturbated, with bedding-plane feeding trails and subvertical burrows.

As others before him, Folk proposed a classification for sandstones based on the relative abundances of quartz (Q), feldspars (F), and rock fragments (R). These are the main poles of the classification diagram. To define the clan name one must normalize the sum of abundances of quartz, feldspars and rock fragments to 100%.1. Introduction. The Northern Iraqi Thrust zone and Foothill zone, where the three studied sections of the present study (Dure, Lefan, and Sinjar) are located, is considered as a good place of mineralization of many ore deposits, especially the lead-, zinc-, and iron-sulfides. This is because the structural, tectonic, and lithologic factors ...

A sedimentary rock consisting chiefly (more than 50% by weight or by areal percentages under the microscope) of calcium carbonate, primarily in the form of the mineral calcite, and with or without magnesium carbonate; specifically a carbonate sedimentary rock containing ...Siltstone forms in low-energy marine environments, and is an intermediate rock type between mudstone and sandstone. While siltstone is a clearly defined rock type, it can still be difficult to know whether a rock you’ve found is a siltstone. It can easily be confused for similar, closely related rocks.

The lower Hanifa consists of predominantly lime mudstone and laminated organic-rich mudstones, which constitute one of the major Jurassic source rocks. The upper Hanifa Member is composed of mostly shallow-water, higher-energy grainstones and packstones, which represent an overall shoaling-upwards sequence in response to carbonate …

Mudstone is made up of fine-grained clay particles (<0.05mm) compressed together. Mudstones form where clay has settled out in calm water - in lakes, lagoons, or deep sea. Flaky mudstone is called shal Similar characteristics apply to impermeable rocks. Slate, marble, mudstone, and granite are all examples of impermeable rocks. ‌‌‌. Another example is shales, as well as unfractured igneous and metamorphic rocks. These rocks do not allow water to pass through their grains because they are so closely packed.The oolitic limestone and sandstone clasts range in size from 1 to 20 cm along the long axis. The mudstone clasts are usually pebble-sized, rounded, and grey to light grey in colour. The micritic limestone clasts are composed mainly of lime mud, with a minor amount of wackestone .

Mudstone is made up of fine-grained clay particles (<0.05mm) compressed together. Mudstones form where clay has settled out in calm water - in lakes, lagoons, or deep sea. Flaky mudstone is called shal brownish gray lime mudstone. It is locally lithographic, stylolitic and abundantly laminated. Stylolitic partings may be closely spaced (< lcm).

This conclusion is based on the lithology, core microfacies, cutting, thin section and log interpretation variability. The study aims to characterize the depositional and diagenetic properties of the Hartha carbonate and their effects on the reservoir quality.In many cases the lime mudstone and wackestone microfacies grade vertically into a mudstone microfacies.
