2021-09-18 10:34:46 Drilling Engineering Problems and Solutions: A Field Guide for Engineers and Students (PDF)

free download https://t.me/geominerals/413

Petroleum and natural gas still remain the single biggest resource for energy on earth. Even as alternative and renewable sources are developed, petroleum and natural gas continue to be, by far, the most used and, if engineered properly, the most cost-effective and efficient, source of energy on the planet. Drilling engineering is one of the most important links in the energy chain, being, after all, the science of getting the resources out of the ground for processing. Without drilling engineering, there would be no gasoline, jet fuel, and the myriad of other “have to have” products that people use all over the world every day. Open / Comment

2021-09-17 20:14:56 Schooner Gulch State Beach, California

At the edge of the Pacific Ocean, the beach at Schooner Gulch State Beach near Mendocino, looks as though its been scattered with oversized bowling balls. Almost perfectly spherical, stones like these have caused wild speculation wherever they’ve been discovered, with answers from aliens to dinosaurs, but the answer is actually simple geology.

Best observed at low tide, the so-called bowling balls are actually a geological phenomena known as “concretion”, sedimentary rock formed by a natural process wherein mineral cements bind grains of sand or stone into larger formations. These boulders are the result of millions of years of concretion and erosion, exposing the hard spheres as the mudstone of the cliffs receded around them.

In the northwestern part of Kimolos, west of the hill “Sklavos”, there is a giant stone mushroom, “Skiadi” as the residents call it. It is a true monument of nature, located in the middle of a barren plateau with wonderful views: it embraces the southwestern and the western coasts of the island (Ellinika, Mavrospilia, Athinias) and a big part of Milos.

Skiadi” is a huge mushroom stone that dominates the middle of a windy small valley in the interior of the island. Cause of its creation is the wind and the different hardness of its consisting rocks
Its base is made of softer material while the top is of harder .
As the wind drifts grains of dust , it scratches continuously the rock, and through the centuries gave it a characteristic, unique form. This process is called ablation.
For its uniqueness “Skiadi” is included in the Atlas of geological monuments of the Aegean and is a sightseeing for tourists.

2021-09-16 23:46:53 Three Sister Rocks of Monument Valley, Arizona

Three Sisters rock formation in Monument Valley on the border of Arizona and Utah, Monument Valley's isolated rock formations are eroded remains of their Rocky Mountain ancestors, formed by sandstone deposits and geologic uplift and then shaped by wind and water. Three main layers of Organ Rock shale, de Chelly sandstone, and Moenkopi shale are visible in many of the buttes. The rock layers formed during the Permian and Triassic Periods several hundred million years ago that have been subjected to differential erosion (by which hard rocks erode more slowly than soft rocks). The results can be quite complex and stunningly beautiful.

Because Monument Valley was formed from several layers of rock with varying hardness, we are left with magnificently sculpted buttes "Three Sister Rocks", the result of millions of years of simple erosion by water, wind and varying temperature

The purpose of the book is to introduce undergraduate students, and others
with a general geologic background, to the basic principles, aspects and methods of structural geology. It is mainly concerned with the structural geology of the crust, although the processes and structures described are relevant also for deformation that occurs at deeper levels within our planet. Further, remote data from Mars and other planets indicate that many aspects of terrestrial structural geology are relevant also beyond our own planet. Open / Comment

2021-09-14 01:48:27 The White Pocket area in Arizona has a really awesome geology – forget the usual horizontal layers, here we see swirls, folds, faults, offsets, all filled out with the craziest colors you could imagine. Understanding what’s happening here and the complex processes that gave birth to these fantastic shapes makes it all even more beautiful, It has twists, multi-color striations of white, yellow, red, orange, and pink, pock marks and pools that sometimes fill with water, mushroom like protrusions, strange bulges that look like brains, polygonal fracturing, and wave-like features. The processes that have given yield to these bizarre rock formations stump even expert geologists. Some think that the area was liquefied in an ancient earthquake which distorted the sandstone layers while they were still soft, before they were buried under the oceans for 100 million years and turned to stone under the enormous heat and pressure.

2021-09-09 19:20:25 This is an amazing example of a synclinal fold in the basin and range Province of the Appalachians. It's a synclinal fold Sideling Hill , Sideling Hill (also Side Long Hill) is a long, steep, narrow mountain ridge in the Ridge-and-Valley (or Allegheny Mountains) physiographic province of the Appalachian Mountains, located in Washington County in western Maryland and adjacent West Virginia and Pennsylvania, USA. The highest point on the ridge is Fisher Point, at 2,310 feet (700 m) in Fulton County, Pennsylvania.

Sideling Hill is a #syncline mountain, in a region of downward-folded (synclinal) rock strata between two upfolded #anticlines. The ridge is capped by an erosion-resistant conglomerate and sandstone of Mississippian (early #Carboniferous) geologic age, the Purslane Sandstone of the Pocono Formation. The ridge's slopes are formed of much more easily #eroded kinds of rock, including the Devonian-Mississippian Rockwell Formation, with long, narrow valleys paralleling the ridge on either side, The #rocks at the cap of the roadcut are the Early Mississippian-aged Purslane Sandstone, more resistant to weathering than surrounding rocks, allowing the ridge to form. The Late #Devonian to Early Mississippian-aged Rockwell Formation, a mixture of #conglomerate, #sandstone, siltstone, shale, and even coal, underlies the Purslane Sandstone

Note : synclinal structure: Often described as a "downfold" or "trough" or "concave fold," a syncline is perhaps best defined as a fold which has the youngest beds in the core or center of the fold.
