Chaos and Stability in Some Modelsagma at the time of eruption can be calculated to have had (.Th/.Th) ~ 5.7 ± 0.7. A valid earlier interpretation was that these magmas formed 7 years before eruption..The 1988 lavas have-compositions consistent with two end-member models. If the magma formed and separated at one instant, then the ma

Higher Order Scalar Difference Equationsstonite, a common phenocryst phase in nephelinites at Oldoinyo Lengai. Olivine melilitites occur at Oldoinyo Lengai and at young tuff cones nearby; these have alkali contents that are abnormally high, even for these rocks. Olivine melilitites cannot fractionate to form phonolites; relatively low-alk

Chaos and Stability in Some Modelstion (P ≤ 200 MPa). Exsolution of an alkali-rich carbonate liquid from a silicate melt during further cooling and differentiation buffers the peralkalinity of the residual silicate liquid at near constant peralkalinity (/Al≈2.15). At very low pressure (P ≤ 35 MPa) and CO. undersaturated condit
