A Striking similarity between the Chicxulub (Yukatan) crater and the Santorini volcano crater

Excerpt: "The whole debate about the genesis of drilled melt and breccias in the Chicxulub crater is conducted with wrong assumptions. The Chicxulub "impact" crater is in fact the caldera of a supervolcano that is created by a huge gas explosion. The volcanic origin is by drilled pure andesite in the center of the structure no doubt proved. The bedrock was blasted in a great extent and widely distributed.

Gravimetric investigations on Yucatan, suggest that the former magma chamber is not limited under the center of the Chicxulub crater. Possibly the dioritic magma chamber reach far to south. It is possible that the crater to south is open (no boreholes). That would be one explanation for the thick breccia units in Guatemala and South-Mexico.

The ascending andesitic melt in the center of the explosion had only a low eruptive potential. There is no evidence of eruptive melt in the breccias outside the crater on the Yucatan peninsula (questionable Y-5A). The caldera after the gas explosion was immediately covered with falling-back debris. The detection of dykes or veins in the bedrock (Ya-1) indicates lateral intrusions from the yet not cooled andesitic melt body (mixed with breccia). In two wells (C-1, Y-1) were found "ash with glass" in depths between 1300 and 1400 m. This is mysterious and would be worth a new analysis.

There are two different types of breccias from the ruined bedrock. There are breccias above the intact bedrock and breccia above the igneous andesite. The breccias above the bedrock has no contact with the melt and are unchanged. The breccias above the andesite (S-1, C-1, Y-1 wells) are melted or are in contact with melt, in decreasing intensity upwards. Possibly the lowest parts of falling-back debris are already fallen in the andesitic melt. A sorting the breccias (called units) make not sense because convective movements in the melt are expected. In the upper part of the breccia-package are smaller components of falling-back debris concentrated and have already stratification. Glass fragments in the melted breccias-package are geochemically different. These fragments belong as the breccia to the falling-back debris after the explosion. Presumably, these glasses come from a mixed melt of igneous andesite and bedrock on top of the eruptive vent. All the others in Central America found glassy spherules and glass fragments have probably not a connection with the Chicxulub event.

The occurrence of shock-generated features is not only an indicator for an impact event, because this is also proved by finds in volcanic structures."

Picture 1. Horseshoe Basin in the western Gulf of Mexico, as compared using (left) the historic NOAA bathymetry map and (right) BOEM’s new map. The basin contains a salt dome at its center and is flanked by salt sheets. Movement of the salt is evident from the network of faults and rifts expressed on the seafloor around the basin, as well as from the sediment debris flows seen falling down the slopes of the basin and onto its floor.

Picture 2. Digital elevation model (DEM) reconstruction of Santorini comparing (a) the present-day topography and (b) the proposed topography prior to the Minoan eruption. The latter shows the reduced size of a Pre-Kameni island, a smaller and shallower caldera harbour restricted to the north, a possibly smaller caldera outlet (dotted blue line) in the north, and a continuous southern caldera rim connecting Thera and Therasia through Aspronisi.
