Abstract:
The southern Vermion mountain is composed of Pelagonian metamorphic rocks. Two different lithologic units are distinguished in this area. The first one consists of the highly metamorphosed rocks of Paleozoic age (migmatites, gneisses with marble intercalations and anatectic granites). The second unit comprises two series: the lower with schists, gneisses and marbles (200 m thick) and the upper with marbles (more than 2500m thick). The age of the rocks in the second unit is Triassic –Jurassic and these are metamorphosed in greenshist facies. During the last 40 years, the marbles of the second u

Rajasthan is known as mineral majestic State as it produces more than 50 types of mineral and rocks. The State is endowed with vast deposits of natural rocks known as “stones” in local parlance and a few important ones amongst them are Granite, Marble, Sandstone, Limestone, Slate and Quartzite. Perhaps, nowhere in the world social, economic and cultural fabric of the society is found to be so intimately ingrained with stone and stone based products as it is in Rajasthan State of India.

The rock mechanical properties under the effect of high temperature present a great significance on underground rock engineering.

Due to thermal cracking, the uniaxial compressive strengths decrease as the heating temperature rises from room temperature to 400°C. Above 400°C, the sandstone exhibits

Expansive soils occurring in arid and semi-arid climate regions of the world cause serious problems on civil engineering structures. Such soils swell when given an access to water and shrink when they dry out. Several attempts are being made to control the swell-shrink behavior of these soils. Soil stabilization using chemical admixtures is the oldest and most widespread method of ground improvement. In this study, waste limestone dust and waste dolomitic marble dust, by-products of marble industry, were used for stabilization of expansive soils. The expansive soil is prepared in laboratory as

ABSTRACT: Triaxial compression tests are used for the evaluation of the behavior of marble rock in the plastic region. Marble samples with a diameter of 60 mm are experimented on a servo-controlled universal testing machine (UTM). The marble rocks are tested under various confining stresses of 4 MPa, 8 MPa, 12 MPa, 20 MPa, and 28 MPa. During the testing, the volume change of samples is determined by quantifying the flow of hydraulic fluid into and out of the triaxial chamber. The test results reveal that marble rock is brittle at low confinement and softens with increasing confinement. The dat

Abstract:
The Lisina phosphate deposit is located in southeastern Serbia, on the territory of Bosilegrad, close to the Serbian-Bulgarian border. Genetically, the Lisina phosphate deposit belongs to metamorphic deposits. A narrower area of the deposit is made up of metamorphic rocks with an intensive presence of granitoid rocks. Phosphorites occur in the contact zone of the metasandstones that make up the basement and the sericitechlorite shale with intercalations of marble and kalkshist in the roof. Raw phosphates can be applied with positive effects as a fertilizer in the territory of the Republic of S

Abstract:
Based on the geological and petrographical studies and chemical analysis of drill-core and outcrop samples, the geology and mineralization at the Phu Lon area are revealed. The Phu Lon prospect is a Cu-Fe-Au-Ag skarn deposit of porphyry-related type. The copper- and iron-rich zones are hosted predominantly in the garnet-pyroxene skarn that is developed metasomatically at the contact between the diorite-monzodiorite intrusions and a marble with minor calcsilicate unit. The main stage of iron mineralization probably took place during the prograde garnet-pyroxene skarn formation and was genetical

Abstract:
Grand Canyon-Parashant National Monument (PARA) in northwestern Arizona has significant paleontological resources, which are recognized in the establishing presidential proclamation. Because of the challenges of working in this remote area, there has been little documentation of these resources over the years. PARA also has an unusual management situation which complicates resource management. The majority of PARA is administered by the Bureau of Land Management (BLM; this land is described here as PARA-BLM), while about 20% of the monument is administered by the National Park Service (NPS; th

Abstract:
The ca. 1.75 to 1.27 Ga Hornby Bay intracontinental basin, in northwestern Canada, includes the Big Bear, Mountain Lake, and Dismal Lakes groups. This paper investigates the original depositional environments, paleogeography, and architecture of these groups and how they correlate in time and space. The Big Bear group comprises mainly immature clastic rocks deposited by high-energy rivers, the overlying Mountain Lake group was deposited by westerly flowing rivers over a much broader region, and, following tectonic uplift and erosion, basal clastic rocks of the Dismal Lakes Group were deposited

Abstract:
Northern Yukon hosts occurrences of Middle Devonian hyper-enriched black shale (HEBS) Ni-Mo-Zn-platinum-group element-Au-Re mineralization, including the Monster River showing in the Ogilvie Mountains. This mineralization has been documented predominantly in the Paleozoic Richardson trough; however, the Monster River showing is atypical, occurring within the Blackstone trough, more than 200 km to the west on the southern margin of the Yukon block. The ambient paleoredox conditions of the marine water column and sediments may be primary controlling factors in HEBS formation. We use major and tr

Abstract:
Effigy Mounds National Monument (EFMO) in northeastern Iowa was proclaimed on October 25, 1949, to protect a significant concentration of Native American burial mounds, many of which were built in the shapes of animals such as bears. Many of these effigy mounds are found atop commanding bluffs flanking the Yellow River at its junction with the Mississippi River. The geology of the monument has not been a central interest in its history, but the rocks contain evidence of millions of years of shallow marine life from the early Paleozoic. Paleozoic fossils were first documented at what is now EFM

Abstract:
The Labrador Sea formed during rifting between North America and Greenland beginning in the Early Cretaceous, with subsequent seafloor spreading from the Maastrichtian (chron C31) to Early Paleocene (chron C27n) that ended by chron C13 (earliest Oligocene). Early Cretaceous rifting resulted in accumulation of Alexis Formation basalt units and Bjarni Formation nonmarine and marginal marine clastic rocks. In the Late Cretaceous, extension focused further offshore as sag basin conditions formed across the shelf, with a basinwide transgression of Markland Formation shale and localized Freydis Memb
