This Memoir covers one of the most important and active exploration reservoirs being pursued by geoscientists worldwide: fine-grained turbidite systems. 28 chapters show the results of an intense research effort in the 1990s that resulted from the discovery of large hydrocarbon accumulations in fine-grained turbidite systems in Brazil, the Gulf of Mexico, West …
Seventeen volcanic tuff samples from Mexico used as natural building stones were studied. These tuffs show highly variable compositions and different porosities and textural properties as well as very different behaviors in regard to salt crystallization.

Most of these sequences start with a basal fluvial or marginal marine conglomerate, which is succeeded by shallow marine fine-grained sandstone, siltstone, and limestone. Some sequences contain finer-grained lithologies in their upper …
Weathered basalt rock. Blue, black, to tan in color. Mexican Beach Pebble is a naturally occurring fine-grained igneous rock that has been tumbled and battered by the ocean shore. Hand-picked from the beautiful beaches of Mexico, it is one of the most elegant pebbles used in landscapes today. Composed mainly of plagioclase and pyroxene minerals ...
From its color (grey) and grainsize (fine), it is a rhyolite [a fine grained, acid igneous rock]. It is far more difficult to erode than the sandstone on the plain, so it forms upstanding ridges and low hills in the landscape.
Basalt is a dark, fine-grained, basic (low silica) igneous rock, often extruded as molten lava from volcanic fissures. Its low silica content means it can flow easily, often building up over the years to form large plateaus.
Source rock evaluation is performed in a prospective block on the western-central flank of the Tampico Misantla Basin (TMB), Mexico, analyzing the Agua Nueva, Pimienta and …

Shale has also been equated with a claystone, which, in turn, has been characterized either as a clay-mineral-rich fine-grained rock or as a clay-size-dominated fine-grained rock. In the last few years, shale-gas and oil researchers have argued increasingly that the fine-grained sedimentary rocks they studied were not ''shale.''

This study utilizes a collection of 53 tuffs from different regions in Mexico that show a diverse range of colors, rock compositions and mineralogy, and heterogeneous rock fabrics indicative of their volcanic origin.
Andesite is a fine-grained rock that forms when the magma erupts onto the surface and crystallizes quickly. Andesite and diorite have a composition that is intermediate between basalt and granite. This is because their parent magmas formed from the …
Fine-grained or glassy textures are common in volcanic igneous rocks. Coarse-grained textures, where individual minerals are visible, are typical of plutonic igneous rocks. Sedimentary grains are often rounded, while metamorphic rocks have elongated minerals.

a very dark green to black, fine-grained rock composed primarily of pyroxene and calcium-rich plagioclase, with lesser amounts of olivine and amphibole batholith a large mass of igneous rock that formed when magma was emplaced at depth, crystallized, and subsequently exposed by …
Ubiquitous in kitchens across Mexico, the molcajete made of basalt — or fine-grained lava rock — have been used for millennia to grind chiles, prepare salsas, and guacamole. The Masienda Molcajetes are handcrafted in Puebla, Mexico, …
Basalt rock is fine-grained, dark-colored volcanic rock with essentially Mg-rich plagioclase and augite. It is basic or low in silica (42-52 wt. %) mafic (Mg- and Fe-rich) rock, with relatively low amounts of total alkalis (Na 2 O and K 2 O). To identify this rock in the field, consider its colors and texture.
Pinnacle Treasure is a fine-grained metamorphic rock, formed 1.75 billion years ago, deep in the earth's crust. Geologically speaking, it is classified as schist. During its transformative creation, clays and muds were subjected to massive heat and pressure forging a stone with enduring strength and durability. ... Arizona and our New Mexico ...

Shale is a fine-grained (grains less than 2 mm) sedimentary rock that is commonly light to dark gray. In the Gigapan image location, the Mancos shale is dark gray. Sandstone grains are coarser than shale. Grains are typically about 2 to 4 mm.
Evidence for fine-grained deposition on the braid plain comes in the form of abundant sandstone rafts, mudclast-rich sandstones and mudclast breccias found in axial deposits. These represent the erosional products of (semi-)consolidated deposits, …

Rhyolite is a highly silicic, fine-grained, light-colored volcanic or extrusive igneous rock. It is a felsic rock with mainly quartz, alkali feldspar, plagioclase, and minor ferromagnesian minerals content.. The word rhyolite …
The result may be a porphyry, a rock in which coarse crystals called phenocrysts are floating in a sea of fine-grained crystals called groundmass. The porphyry shown if Figure 6.6 includes large phenocrysts of both gray quartz (a bit hard to see) and slightly pinkish blocky K-feldspar. The phenocrysts are surrounded by dark fine grained groundmass.
