Hollow apatites in a layered basic intrusion, Norway
Summary Cumulate apatite crystals with infilled tube-like cavities parallel to the c -axis are described from a layered gabbro intrusion in Northern Norway. These are considered to be skeletal crystals produced by rapid growth in the supercooled roof zone of the magma chamber. At least two stages of...
