Abstract
Tebing Breksi Geotourism Object is one of geotourism object in Yogyakarta which part of UNESCO Gunung
Sewu Geoheritage. Geologically, Tebing Breksi is included in Semilir Formation that consists of volcanoclastic
sediments such as Tuff, Tuffaceous sandstone, Tuffaceous claystone and lapilli (Surono, 2009). This research is
trying to apply digital technology to geological science through 3D Outcrop Model in order to understanding
history, sedimentary process and depositional environment easier. The Digital outcrop model was build up by
photo that acquired by drone with systematic captured. Sedimentology data was captured by conventional method
and measuring section that represents all layers. Based on model and data, it shows the dynamics of sedimentary
process from bottom to top and could be identified from sedimentary structures and lithofacies. Bottom part shows
bedding structures that describe grain size changing from sandstone to conglomerate and refer to model (Kendall,
2004) match on Supra Fan Lobes, the middle part displaying a bedding structure and coarsening upward stacking
pattern and interpreted as inner fan channel facies and the upper part is new sequence package interpreted as basin
plain. As a whole, the volcaniclastics sediment in Tebing Breksi area was from great Semilir Eruption in Early
Miocene (Smyth, 2011) which was deposited in submarine fan system to basin plain (Kendall, 2004). This model
is being developed with additional data to be an Augmented Reality (AR) smartphone application for other
purposes.
