Chert concretions in thick limestone successions preserve a more complete paragenetic sequence of diagenetic minerals than their host and interbedded shale. The goal this study was to test the possible presence high-temperature mineralising system Ionian basin western Greece. Upper Cretaceous chert nodules were sampled at Araxos, where rocks are highly faulted uplifted by salt diapirism, on Kas...

By harnessing both hypothetical, synthetic basin and gas hydrate (GH) system models real-world of well-studied salt diapir-associated GH sites at Green Canyon (Gulf Mexico) Blake Ridge (U.S. Atlantic coast), we propose demonstrate movement (and in particular, diapirism) to be a new mechanism for the recycling marine GH. At Canyon, example, show that by considering this newly proposed diapir-dri...

Geomorphosites or special geomorphologic sites are new concepts which have entered tourism literature with anemphasis on special sites. Basically, the goal for discussing such concepts is to identify landforms with specialimportance on understanding the geomorphologic structure of a region and their scientific, ecological, cultural,aesthetic, and economical values. Generally, they are used for ...

Mudboils are round to elongate, 1-3 m diameter bare soil patches that form on perennially frozen till. marine clayey silt, colluvium. or other poorly sorted sediments (muds) with significant silt and (or) clay content. In Keewatin these muds have low liquid limirs (<ZM) and limited plasticity indices (<It)%). Natural moisture contents are very near the liquid limit .w thal rhe muds liquefv and ...

Inherited and syn-compressional salt-controlled structures in orogens are difficult to distinguish from compressional features because classical salt (halokinetic growth strata, welds) can be misinterpreted as shortening-related (syn-kinematic tectonic unconformities). In the Sivas basin Turkey, syn-kinematic diapirism entirely shaped architecture of foreland allowed development primary seconda...

Magnetization by core dynamo activity in large asteroids and planetesimals is suggested the remnant magnetization of many achondritic meteorites. However, conditions for a sustained such small bodies problematic several reasons. Such may not have energy budget or size to achieve sufficient dynamo. Moreover, given their low internal pressures, planetesimal cores likely freeze from top down, wher...

S U M M A R Y Many unresolved questions in geodynamics revolve around the physical behaviour of the two-phase system of a silicate melt percolating through and interacting with a tectonically deforming host rock. Well-accepted equations exist to describe the physics of such systems and several previous studies have successfully implemented various forms of these equations in numerical models. T...
