When huge masses of salt move underground: lessons from outcrops that go beyond the table salt

When huge masses of salt move underground: lessons from outcrops that go beyond the table salt

There is a place in the NE of Mexico where anyone can learn heaps about the dynamics of the ground beneath our feet while enjoying the wonders of the desert. Geologists call the area ‘La Popa Basin’. La Popa means “The Bow”, a name that comes from the shape of one of the mountains in this area, which resembles the front part of a very large boat. This place is a perfect training field for ge ...[Read More]

Alberta’s Geological Riches

Alberta’s Geological Riches

Smoky Summer It has been a difficult summer in Alberta, with smoke from forest fires in British Columbia blanketing much of the southern part of the Province. However, this has not stopped me getting out into the field on a variety of projects and hikes, including a virtual field trip looking at the Cardium Formation and several in person trips to the beautiful Sheep River Provincial Park and surr ...[Read More]

Sediment in the deep ocean. Part 2: thermohaline currents that shape the seafloor

Sediment in the deep ocean. Part 2: thermohaline currents that shape the seafloor

In Part 1 we differentiated between (1) shallow-marine tide-related currents from (2) purely gravitational sediment-laden currents. We could add that the former are periodic, as they are controlled by the effect of the Moon and Sun gravitational fields on the oceanic water as the Earth revolves, while the latter are sort of ‘spontaneous’ currents driven by the Earth gravitation field on sedi ...[Read More]

An online learning platform for cyclostratigraphy – www.cyclostratigraphy.org

Cyclostratigraphers aim to read and understand the effect of climate-driven orbital changes in the geological record through time. In doing so, they start from an important prerequisite: An imprint of insolation variations caused by Earth’s orbital eccentricity, obliquity and/or precession (Milankovitch forcing) can be preserved in the geological rock record. The new www.cyclostratigraphy.org webs ...[Read More]

Sedimentology – towards a disciplinary crisis?

This contribution adds to earlier articles on impact of global change on sedimentology and on the changing role of sedimentologists in a society moving towards a carbon-free energy future (e.g. Simmons and Davies, 2020, SSP BLOG). Sedimentology is a child of the Age of Petroleum. And, the success story of petroleum is closely linked to the equally successful story of gasoline-powered mobility. Let ...[Read More]
