The Ocean Floor Bethany Ostlund 4th Grade The Ocean Floor
... In the following diagram there is evidence of seafloor spreading by showing the ages of the ocean floor. The red colors are the youngest parts of the seafloor, where fresh new crust is formed as lava seeps up from the deep interior of the Earth at spreading ridges. The green colors are the spreading ...

Accommodating sill-complex emplacement

These analyses highlight that the behaviour of the host rock during emplacement strongly influences forced fold evolution and may also determine whether additional space-making mechanisms occur (e.g., ...

Layering in the wall rock of Valles Marineris: intrusive and extrusive
... within terrestrial cumulate rocks can vary from tens of meters to centimeters. Though the origin of layering in intrusions is poorly understood, it is generally interpreted to result from fractional crystallization and sedimentary processes during crystallization in cooling magma chambers. Examples ...
