Kerkenes Dag lends itself particularly well to magnetometry because it was all burnt once in a savage fire. In places the heat was sufficient to turn sandstone to glass and to melt granite. The fire was so hot that there were strong magnetic signatures set to the Earth’s magnetic field fr...

How does a longshore current change a beach? How do sandbags prevent coastal erosion? What are the effects of coastal erosion in Holderness? How does sandstone change into quartzite? How do uplift and erosion help to form a batholith? How does volcanism increase the rate of chemical weatherin...
Mathematical calculations of thermal convection, however, demonstrated that even thin interbedded layers of mudstones within permeable sandstone sequences will split potentially larger convection cells into smaller units of sandstone beds which may then be too small to exceed the critical Rayleigh number....
take Needles Overlook Road, which takes off a few miles before the correct junction. This road does not take you to Canyonlands National Park. Watch for the Canyonlands National Park sign before turning. From Monticello drive 14 miles north on U.S. 191 and turn left (west) onto S.R. ...
Crystal opal: Fully transparant or almost translucent clear opal. Also known as jelly opal or. Mostly covered in a dark to light grey clay like sandstone. In my experience this material is stable but more prone to chipping than white opal. Hydrophane qualities differ a lot. The color pattern...
Just 50 years ago, no one knew why the Earth has mountains. Now we do. This is the story of how we figured it out - and how we keep learning.
settled, layer upon layer piled up on the sea bottom trapping the organic material. Without air, the organic layers could not rot away. Over time, increasing pressure and temperature changed the mud, sand and silt into rock and slowly “cooked” the organic matter into petroleum and natural ...
Why would the landscape ecology of karst aquifers vary from that of an unconsolidated sand aquifer? What factors affect the absorption of groundwater into the stem of a plant? Describe the process of coastal aging/smoothing. What ...
