Abstract. Recent U–Pb dating by laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) has demonstrated that reasonable precision (3 %–10 %, 2σ) can be achieved for high-resolution of texturally distinct calcite phases. Absolute dolomite, which biostratigraphy and traditional techniques are very limited, remains challenging, although it may resolve many fundamental questions re...

Greenschist facies metabasite (chlorite schist) and metasediments (banded iron formation (BIF)) in the Wutai Complex, North China Craton recorded extensive fluid activities during subduction-related metamorphism. The pervasive dolomitization chlorite schist significant dolomite enrichment at BIF–chlorite interface support existence of highly channelized updip transportation CO2-rich hydrotherma...

The deeply buried carbonate reservoir of Cambrian is an important target oil and gas exploration in the Tarim Basin. Understanding dissolution mechanism deep-buried urgent problem to be solved. In this study, 11 samples from three types deep reservoirs Basin were selected as experimental objects, process was simulated by using advanced reaction system continuous flow at high temperature pressur...

The Zagros Fold and Thrust belt is one of the world's most prolific petroleum provinces. Most hydrocarbon reserves are stored in naturally fractured reservoirs such fracture systems can therefore have a significant impact on reservoir performance. Fractures important paths for fluid flow carbonate reservoirs. Fracture data were collected outcrops Kirkuk Group Oligocene age around Qara Chauq Sou...

This study investigates reservoir quality for the Middle–Late Eocene Pila Spi Formation in Shaqlawa (Sarkand) and Gulley Keer (Shekhan) areas Kurdistan Region of Iraq. Lithologically, studied sections is composed limestone, dolomite, dolomitic chalky marl. The thickness formation about 102m 200m Sarkand Gully respectively. In order to evaluate characterization formation, different techniques su...

The research on the developmental characteristics and evolution process of pores in dolomite reservoirs is a hot spot petroleum geology. In this paper, taking Longwangmiao Formation Gaoshiti area as an example, differential distribution pore parameters have been systematically studied combined with downhole cores, logging, cast thin sections, scanning electron microscope data. We used statistic...
