Abstract:

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.

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

This paper introduces a new technique for the quantitative analysis of ceramic thin sections through petrography. The technique is a version of point counting that estimates with considerable precision the amounts of human additives (temper) and natural inclusions (silt and sand) in ceramic pastes. In concert with traditional qualitative identification of mineral inclusions, this technique expands the capacity of petrography to shed meaningful light on such topics in ceramic analysis as technology, production, trade, and classification.

This study analysss the quality of sand stone as reservoir in Sentul Formation, Tarakan Basin, based on petrography and routine core analysis. The quality of the sandstone in facies A (depth of 1743.75–1747.28m) is moderate. This assessment is based on the porosity value of routine core analysis from 19.48% to 27.88%, and permeability value from 25mD to 213 mD. The sandstone quality of facies B (depth of 1741.80 m–1743.75m) is good, this is based on the value of the porosity from routine core ranges from 23.34% to 26.71% and 83-359 mD of permeability value.

Ductile components including rock fragments, clay, and matrix material are often consideredas the most important factors that control quality of shaly sandstones, which areusually characterized by low porosity and permeability. In presence of ductile components,the degree of quality reduction is affected mainly by distribution, occurences, andamounts of the ductile components. Therefore, the presence of ductile components affectsrock petrophysics, and consequently has effect on fluid movements in reservoir duringproduction.This paper presents results of the study on plug samples taken from fiv
