Résumé :

Hohokam buff ware pottery produced in Arizona has been much studied over the last few decades. However, petrographic analysis has been less frequently applied, due in part to mistaken assumptions regarding the raw materials utilized. The current study reexamined the use of petrography for locating the provenance of buff ware pottery from two sites, La Villa in the Phoenix area and Honey Bee Village in the Tucson area. The petrographic results suggest that production occurred in one primary area along the middle Gila River with minor production in a few other locations. The potters in this area

The similar material composed of quartz sand, gypsum, colophony and alcohol solution, model test and similarity theory were depended on in the test, and standard cylinder specimens were made in different proportions. The physical and mechanical properties of blocks were studied through uniaxial compressive experiments. The researches show that the ratio of elastic modulus and down modulus of the specimens increase linearly with the increase of the ratio of sand and cement; while the elastic modulus, the down modulus and the uniaxial compressive strength decrease in shah model of index function

The quartz sand of the Lower Cretaceous Robbedale Formation and lowermost part of the Jydegard Formation in the Arnager-Sose fault block of Bornholm has been investigated with respect to mineralogy, grain-size, grain rounding and grain shape. Analyses of both light and heavy minerals have been carried out for 18 samples from different localities and facies. The purpose of the investigation was to try to recognize the possible types of source rocks and provenance areas. The Precambrian basement rocks of Bornholm are not the main sources of the sand, especially not the heavy minerals, but parts

Concrete structures may develop deleterious damage, which significantly reduces service life, structural integrity, and safety, posing serious issues in large or otherwise critical infrastructure. Routine petrographic assessments, including microstructure, texture, and fabric, of concrete and its (gravel and sand) aggregate and binder constituents in thin section using polarization-fluorescence microscopy (PFM) enables the unequivocal identification of features that would otherwise remain hidden in conventional petrography. Rigorous preparation procedures preserve original microstructural deta

ABSTRACT We used high-resolution petrographic and dense-mineral data on modern sand to investigate erosion patterns of the El Rosario, San Fernando, and San Vicente river basins of Baja California (Mexico) to better understand the interrelationships between a complex magmatic arc terrane and surface processes. Modern sand composition of these three rivers reflects the nature of the source region, which lies in the central part of the Alisitos arc (Peninsular Ranges, Baja California, Mexico). The sand detrital modes correspond well with the main structural units drained by the El Rosario, San F

The study of petrography is a primary step in provenance research of beach sand sediments. The data set needs to be analyzed for this study is based on their mineralogical compositions and structure. The study of sediments in the present-day depositional environment is important to find out the nature of sediments to reconstruct the history of rock including information about the origin of its constituent particles, the method and distance of sediment transport and the nature of the place where the grains eventually came to rest i.e. the environment of deposition.

Sediment petrography and heavy mineral analysis represent two key techniques to decipher the pieces of information stored in the sedimentary record, shedding light on source rocks compositon, weathering conditions and paleodrainages. Traditionally, even though orogenic detritus has always received large attention, orogenic provenance has been recognized as “composite”, thus preventing clear classification. Notwithstanding the composite nature of collision orogens, the detrital fingerprints of neometamorphic axial belts, largely experiencing strong exhumation and erosion, can be regarded as th

Résumé :

This Open File report provides petrographic information from a scanning electron microscope study of granules and small pebbles in four selected trawl samples from Flemish Cap. The mineral composition of the granules was determined by energy dispersive spectroscopy (EDS) and textures are shown in backscattered electron images (BSE). It complements Open File 8359 on the heavy mineral assemblage on Flemish Cap. Granules on the central shoals appear to be derived from outcropping Avalonian basement; those to the east and west are predominantly ice-rafted in origin. These data improve our understa
