    Description / Table of Contents: Abstract From 1960 to August, 1966, the activity of Oldoinyo Lengai took the form of quiet extrusion of carbonatite lava. In August, 1966, the style of activity changed abruptly and violent ash eruptions took place. The activity varied from minor emissions of ash to major Plinian and Vulcanian type eruptions. A new ash-cone built up within the crater and ash was widely distributed on the slopes of the volcano and over the surrounding countryside. The ash consists of sodium carbonate mixed with crystals of nepheline, pyroxene, wollastonite, apatite, melanite and pyrite. Also blocks of ijolite and melteigite were ejected during the activity.
    Abstract: Résumé De 1960 jusqu'en août, 1966, l'activité du volcan Oldoinyo Lengai consistait en coulées tranquilles de lave carbonatitique. En août, 1966, le genre d'activité changea abruptement et de violentes éruptions de cendres se produisirent. L'activité consistait tantôt en de petites émissions de cendres, tantôt en éruptions majeures du genre Plinien et Vulcanien. Un cône neuf de cendres s'amoncelait dans le cratère actif, et les cendres se dispersaient sur le pays environnant. Les cendres se composaient de carbonatite alcaline avec des cristaux de nephéline, pyroxène, wollastonite, melanite et de pyrite. D'ailleurs des blocs d'ijolite et de melteigite furent projetés hors du cratère pendant l'activité.
    Notes: Zusammenfassung Von 1960 bis zum August 1966 bestand die Tätigkeit des Vulkans Oldoinyo Lengai/Ostafrika in ruhigen Lava-Extrusionen. Im August 1966 änderte sich plötzlich die Art seiner Tätigkeit, und heftige Aschenbrüche fanden statt. Diese Tätigkeit variierte von kleineren Ascheneruptionen bis zu größeren Ausbrüchen plinianischen und vulkanischen Typs. Ein neuer Aschenkegel entstand in dem aktiven Krater, und Asche wurde weithin über die Abhänge des Vulkans und über die Umgebung verteilt. Die Asche besteht aus Natrium-Karbonatit mit einer Beimischung von Kristallen von Nephelin, Pyroxen, Wollastonit, Apatit, Melanit und Pyrit. Während des Ausbruchs wurden auch Ijolith- und Melteigitblöcke ausgeworfen.
