Description:
During the Roque Nublo volcanic cycle and sometime between 3.9 and 3.0 million years ago, a number of small strombolian eruptive centres had formed on the flanks of the central stratovolcano. One of these, the most important one and which forms part of an alignment of three eruptive cones along a fissure on the south-western flanks, is the Cuevas del Rey eruptive center, located just below where the Roque Bentaiga stands today, forming part of the Three Kings. This image is a close up of one of two rocky outcrops which are the highly eroded remains of the inside of the crater belonging to this strombolian cone, which is believed to have measured 1 km in diameter. The red rock is composed of a mixture of intra crater lapilli, breccias, debris, scoria and bombs, these vivid red tones created by the oxidisation of iron within the rocks by the residual hot, water vapour rich gases escaping from the crater after the eruptions had ceased. The two monoliths forming these remains are also cut by basaltic and phonolitic dikes of Roque Nublo age. The basement which forms this eruptive centre is geologically very complex since this strombolian cone stood exactly on top of the focal point of the previously emplaced plutonic syenites and cone sheet intrusions. The formations below are comprised of the structurally uplifted layers of fallout pumice, epiclastic materials and the caldera fill ignimbrites, which were intruded into by syenite stocks and are crossed by numerous dikes both of Roque Nublo age and of the previous cone sheet formation. Interestingly there are also breccias that seem to correspond to an older eruptive centre, although no evidence of this centre has ever been found. If it were to have existed, then all the materials emitted have been completely eroded away.
