Nonlinear Dielectric Susceptibilitiesssing model developed by Jaupart and Vergniolle (1988, 1989), and suggest that the shallow plumbing system comprises several small (<10-m radius) chambers containing transient foam layers which may, in turn, be connected at depth to a single, larger chamber.

Field Observations and Measurements of the Physical Properties of Oldoinyo Lengai Alkali Carbonatitd that lava flows erupted on Oldoinyo Lengai are smaller, though morphologically similar to basaltic lavas erupted on Mount Etna and Hawaii. Factors governing flow lengths, morphology and the development of compound flow fields on Oldoinyo Lengai are identical to those on basaltic volcanoes.

Nonlinear Dielectric Susceptibilitieshelinite lava is documented. The CL spectroscopy shows that Mn. is the main activator in wollastonite, combeite, and in the green cores of apatite. The spectral analysis of blue apatite indicates REE activation, considered typical of apatites from carbonatites.

6.1.1.3 Crystal-name abbreviations,er slightly depleted relative to bulk Earth and CHUR. Isotopic variations indicate that the rocks from Oldoinyo Lengai cannot be derived by magmatic differentiation alone; at least two spatially related components are involved in the origin of rocks from Oldoinyo Lengai.

An Assessment of the Alleged Role of Evaporites and Saline Brines in the Origin of Natrocarbonatiteclearly magmatic. If natrocarbonatites were either remobilized or dissolved trona deposits, the resulting melt would have to acquire almost all of the chemical features observed in known carbonatites from East Africa.
