Abstract:

Petrographic analysis is not new to the study of archaeological ceramics, but it is receiving more attention as it is applied to interesting and diverse archaeological problems. Petrography was developed by geologists to identify minerals in rocks. Archaeologists use it to study the minerals that occur in prehistoric clay matrices transformed by heat to a rocklike state.Petrographic analysis requires a polarizing microscope and a piece of ceramic, called a thin section, 30 microns (0.03 mm) thick. As light from this specialized microscope passes through a mineral, it produces optical propertie

Purpose. To determine the rock composition and origin of raw materials of non-flint stone products found during the study on the Mira Upper Palaeolithic archaeological site in the Middle Dnipro area. Methodology. The research on the artefacts was carried out using the mineralogical and petrographic methods. The rocks were studied in transparent thin sections using a polarized microscope. To verify the accuracy of the petrographic analysis of some specimens, the XRD and XRF methods were applied.

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

Abstract Regional stream sediment surveys are an important exploration tool used in the search for concealed or partially concealed porphyry deposits. It is shown here that quartz contained in the coarse fraction of stream sediments can be used as an indicator mineral to supplement geochemical analyses conducted on the fine fraction, such as the measurement of the bulk cyanide leach extractable gold content. A method is proposed that allows separation of quartz grains from the coarse rejects of stream sediment samples to prepare grain mounts for petrographic analysis. Based on optical cathodol

Abstract:

During the last thirty years, microstructural and technological studies on ceramic glazes have been essentially carried out through the use of Scanning Electron Microscopy (SEM) combined with energy dispersive X-ray analysis (EDX). On the contrary, optical microscopy (OM) has been considered of limited use in solving the very complex and fine-scale microstructures associated with ceramic glazes. As the crystallites formed inside glazes are sub- and micrometric, a common misconception is that it is not possible to study them by OM. This is probably one of the reasons why there are no available

Image analysis is a fast and accurate technique for measuring the relative amounts of various mineral components of a rock. In a routine scanning electron microscope (SEM) based modal analysis, backscattered electrons (BSE) are used to generate average atomic number contrast to determine the presence of the various minerals. The minerals are then identified with the use of an energy dispersive (EDS) or a wavelength dispersive spectrometer (WDS). Once a mineral is identified, its modal percent can be calculated by comparing the area of pixels which the mineral occupies with the total area scann

The Phrao-Wiang Pha Phao granitic rocks are crop out along Highway Number 1150 (Phrao-Wiang Pa Pao) in Chiang Mai and Chiang Rai provinces. The geologic investigation as field observation, lithology, petrography, geochemistry, and tectonic interpretation applied for this study. The least-altered 19 rock samples were collected and performed in stained rock slabs for modal analysis and standard thin sections for petrographic analysis. Based on the Quartz-Alkali Feldspar-Plagioclase diagram for plutonic rocks, the rock samples in the Phrao area are granodiorite, and one is biotite-monzogranite, w

Abstract:

The Meluhu Formation consists of quartz sandstone, red shale, siltstone, and mudstone at the bottom part, and alternating black shale, sandstone, and thin limestone in the upper part. Petrographic components composition can reveal the litho-tectonic setting of a region. The composition of sandstone can be done by determining and counting the proportion of a quartz minerals, feldspar, and rock fragment from thin sections using petrographic analysis. This result can guide to depositional setting and paleoclimates of a region. The Provenance and paleoclimates studies of Meluhu Sandstone are still

The China-Pakistan Economic Corridor (CPEC) is a massive in-progress construction project in Pakistan that connects more than 70 countries via multiple trade channels such as highways, railways, roads, and fiber optics. This project also involves the development of local infrastructure and industrial zones in Pakistan, which demands the discovery of new resources of aggregate to facilitate the construction. Therefore, physical characterization research was carried out on the Kirman hill region (Jurassic limestone), District Kurram, Pakistan, to investigate their suitability for utilization as

This study focuses on the examination of aspects of the carinated pottery of the Dvaravati period. This type of pottery is one of the most prominent types found in a large number of Dvaravati sites in Thailand. Samples used for this study were collected from excavations at archaeological sites located in several regions of Thailand including Northern, Northeastern and Central Thailand. The carinated potteries were analyzed using petrographic analysis. The objective of this work was to examine the pottery fabric. This method is used to establish sources of raw materials, and whether production

Abstract:

By comparing thin sections of basalt artifacts from three early and middle Holocene Aleutian sites with geological samples, we can infer the location of the artifactual rock source or sources. Contrary to the sources, the comparison shows that the basalt artifacts came from a single flow or closely related flows 15-30 km from all three sites. This finding suggests we should reassess the role of cultural continuity, trade, and exchange in the early and middle Holocene of the Aleutians.

Abstract:

AbstractMany subjective descriptive terms such as ‘smooth’, ‘coarse’ and ‘anisotropic’ are routinely used to convey properties of textures and fabrics, but these aspects of geological objects are not easily quantifiable. The use of directional semivariograms of image greylevels is assessed for this purpose. These quantify anisotropy of ‘coarseness/fineness’ by using semivariogram ranges, and ‘roughness/smoothness’ by using semivariogram sill values. These can be summarized by ellipses derived from semivariogram ranges and directions. The method will find applications in analysis of rock thin s

Abstract:

Petrographic study of sedimentary rocks can be used to determine provenance and diagenetic histories. Thirty samples from Kussak Formation were collected from Khewra Gorge, Eastern Salt Range, Pakistan, for petrographic studies. Petrographic analysis revealed that Kussak Formation consists of quartz with mean value of 85.2%, while feldspar accounts for no more than 3% of total grains. Lithic fragments and a variety of heavy minerals were observed in traces and cumulatively amounts to 2.5%. Silica, calcite, and iron oxide, as cementing materials, were also detected in sandstone and contribute 4
