PHOTOS FROM THE EL LACO MAGNETITE DEPOSIT:

Photo 1 - Bedded hematite ash and lappilli. This deposit is composed of loose, uncemented, material that can be dug out by hand. El Laco sur.

Photo 2 - Bedded hematite ash with in situ magnetite spindle bombs. El Laco sur.

Photo 3 - Magnetite spindle bombs collected in situ from loose, bedded hematite ash. Some of the spindle bombs had well developed bomb sags beneath them and bedded ash drapped over their tops.
