Tectonic Record of Deformation in Intraplate Domains: Case Study of Far‐Field Deformation in the Grands Causses Area, France

open access: yesGeofluids, Volume 2020, Issue 1, 2020., 2020
Although tectonic plates are usually considered as rigid blocks, intraplate deformation such as lithospheric buckling or diffuse brittle deformation has been recognized for a long time. However, the origin of these deformations remains puzzling. Indeed, whereas the chronology of deformation at plate boundaries can be constrained by numerous methods ...

Provenance and geochemistry of exotic clasts in conglomerates of the Oligocene Torehina Formation, Coromandel Peninsula, New Zealand [PDF]

open access: yes, 2003
Non-marine pebble to cobble conglomerates of the lower Torehina Formation (Oligocene) crop out along western Coromandel Peninsula and overlie, with strong angular discordance, continental-margin metasedimentary rocks (Manaia Hill Group) of Mesozoic (Late

Fracture, Dissolution, and Cementation Events in Ordovician Carbonate Reservoirs, Tarim Basin, NW China

open access: yesGeofluids, Volume 2020, Issue 1, 2020., 2020
Ordovician carbonate rocks of the Yijianfang Formation in the Tabei Uplift, Tarim Basin, contain deeply buried (>6000 m), highly productive oil and gas reservoirs associated with large cavities (>10 m). Previous workers inferred that large cavities are paleocaves (paleokarst) formed near the surface and subsequently buried.

The Hydrogeochemical Stratigraphy of Brines and Its Implications on Water Management in the Central Jordan‐Dead Sea Rift Valley, Israel

open access: yesGeofluids, Volume 2020, Issue 1, 2020., 2020
The exploratory borehole Megiddo‐Jezre’el 1 (MJ1) was drilled in Israel, in the Bet She’an Valley which branches out from the Central Jordan Rift. It reached the depth of 5060 m and bottomed within the Upper Triassic Mohilla Fm. Following the increase of groundwater exploitation, the Cl- concentrations increased and ionic ratios changed indicating ...

Pliocene Te Aute limestones, New Zealand: Expanding concepts for cool-water shelf carbonates [PDF]

open access: yes, 2003
Acceptance of a spectrum of warm- through cold-water shallow-marine carbonate facies has become of fundamental importance for correctly interpreting the origin and significance of all ancient platform limestones.

An Impressive Impact on Well Productivity by Hydrochloric Acidizing of Vuggy Carbonate Reservoir: A Case Study [PDF]

open access: yesIranian Journal of Oil & Gas Science and Technology, 2017
Hydrochloric acidizing is a routine operation in oil fields to reduce the mechanical skin. In this paper, practical acidizing in a typical carbonate oil reservoir located in the southwest of Iran is practiced, which shows an unexpected improvement after ...

Les Gorges de Trévans dans le front subalpin – Un site exceptionnel des Alpes de Haute-Provence

open access: yesPhysio-Géo, 2011
The canyon system of Trevans has cut the blocks of the jurassic limestones, in subalpine over thrust front, near the Valensole piedmont. These landforms are in relationship with the neotectonic movements.

Isotopic characteristics of carbon and oxygen within ordovician carbonate paleokarst in the tazhong region and their paleoenvironmental significance

open access: yesFrontiers in Earth Science, 2023
The Tazhong region is a key area for oil and gas exploration and development within the Tarim basin. In this region, development of Ordovician carbonate paleokarsts has been found to be extremely heterogeneous.
