If either of these sedimentary features appear as inverted in contrast to the normal orientation, then it should be concluded that the sedimentary layers have been overturned by tectonic forces. With inverted graded bedding, grain size will dec ...

K-Ar age determinations of the Alta
... The rocks of the Alta-Kvænangen window have low potassium concentrations which strongly limit the choice of the samples for K-Ar dating purposes (Table 1). It was also impossible to carry out mineral separations because of the ophitic texture in the unaltered rocks; in the altered rocks metamorphic ...

volcanic activity
... Common Parts of a Volcano Within a volcano, there is a portion that fuels the eruptions. This is referred to as the magma chamber. Once the magma chamber is fueled, it erupts through an opening in the crust. This opening is called the vent. Over time, the lava will solidify and accumulate to form a ...
