“Flames Over Persepolis”: New Scientific Evidence Supporting Historical Perspectives

Archaeometry, EarlyView.
ABSTRACT This study investigates the burning of Persepolis Terrace, historically attributed to Alexander III in 330 bce. A review of classical accounts and excavation reports, combined with diagnostic surveys, confirms the fire's historicity and provides novel insights.

An Archaeometric Approach to Reveal Organic Compounds via GC‐MS Analyses of Two Discovered Incense Burners at Daba Al‐Bayah

Archaeometry, EarlyView.
ABSTRACT This study focuses on two terracotta incense burners discovered in the Daba Al‐Bayah necropolis in the Musandam Peninsula (Oman), associated with an Iron Age collective tomb (LCG‐2). Through gas chromatography–mass spectrometry (GC‐MS), the organic residues preserved within these artifacts were analyzed to investigate their use and ...

Deep Groundwater Total Dissolved Solids Mapping in the Dakota Group, Williston Basin, USA

Groundwater, EarlyView.
Abstract Growing concern about the quantity of available freshwater around the world has led to interest in surveying groundwater total dissolved solids (TDS) below water well depths. Deep TDS has not been systematically mapped, and there is much to learn about the distribution and controls on deeper groundwater. In sedimentary basins across the United

鄂尔多斯盆地姬塬地区长6 储层矿物含量与孔隙度的线性关系 [PDF]

, 2019
矿物含量是影响储层物性的重要因素之一。为了较全面地分析不同类型矿物含量对储层孔隙度的影响，以鄂尔多斯盆地姬塬地区长6 砂岩储层为例，探索性地运用多元逐步线性回归法分析了石英含量（x1）、长石含量（x2）、岩屑含量（x3）、绿泥石含量（x4）、伊利石含量（x5）、高岭石含量（x6）、硅质含量（x7）以及铁方解石含量（x8）与孔隙度（y）的关系，建立了矿物含量（xi）与孔隙度（y）之间的回归模型：y = 21.131-0.086 x2-0.113 x3-0.554 x4-0.370 x5-0.199 x6 ...

Determining impact angle from the spatial distribution of shock metamorphism: A case study of the Gosses Bluff (Tnorala) impact structure, Australia

Meteoritics &Planetary Science, EarlyView.
Abstract The majority of planetary impacts occur at oblique angles. Impact structures on Earth are commonly eroded or buried, rendering the identification of the direction and angle of impact—using methods such as asymmetries in ejecta distribution, surface topographic expression, central uplift structure, and geophysical anomalies—challenging. In this
