| Abstract: | The coming together of basic and acid magma in a volcanic plug is believed to have produced above-liquidus temperatures and effected temporary fusion of oligoclase phenocrysts in the acid component. Electron-probe analyses of the minerals show a high degree of feldspar ternary solid solution which is related to composition of the magma and possibly to the effect of superheating. |
