| A serpentine flow meanders through formations of smooth pahoehoe lava and rough aa lava, the same forms common in basalt lavas. |
| Eastwards, the basalt flows become thinner and interfinger with red lacustrine or sabkha siltstones deposited in the deeper parts. |
| Here the rock formed when lava flowed into a freshwater lagoon and quickly altered into spilite basalt. |
| Soils on basalt had a higher pH and were higher in most micronutrients, but lower in Iron, than soils on arkose. |
| Here, spectacularly large groups of scolecite, heulandite, apophyllite, and associated minerals occurred in cavities in flood basalt. |
| It can be found in fissure veins and brecciated amygdaloidal basalt lodes but not in the conglomerate lodes. |
