Tectonic Evolution of the Southern Negros Geothermal Field and Implications for the Development of Fractured Geothermal Systems

Figure 2

Geological column of the CDN volcano as encountered in the boreholes. Corresponding ages are in the first column, whilst their general lithologies are in the third column. Note that although there is a strong geochronological evidence that the Nasuji Pluton is younger, there is no clear evidence of its intrusion into the younger lithologies.
