South-east, the contact between ophiolites and Quaternary alluvia shows rectilinear segments roughly N60E and N-S. They are referred to as faults. The presence of alluvial fans suggests important vertical movements which could be explained by late extension faults at the back of theo verthrust. Left lateral shifts along some N-S faults are in agreement with observations at the Ulugan and Rizal faults. CONCLUSION For this synthetic map, remotely sensed documents are used as a basis to homogenize, verify, reevaluate and extrapolate all the elements which are finally reported. Satellite imagery is a useful tool for integrating such diverse features as field observations, seismic and well data and bibliography. Faults, fractures and joints are clearly expressed on the images so that the tectonic pattern is completed. Some hypothesis made on images about the succession of phases, once localy confirmed by microtectonics, can be extended to broad areas. On such a map, it is important to clearly discriminate confirmed and assumed data. Concerning Landsat imagery, which is quite inadequate to tropical areas it is shown that band 7 can bring useful information. Good results in both lithology and tectonics are mainly based on physiographic observations. As already mentioned by Floyd and Sabins (1980), the SIRA radar images provide good lithological studies, but slopes and drainage patterns are insufficiently detailed for precise tectonic interpretation. However dense vegetation and alteration of rocks may induce many artefacts. For example, two different series, with a similar lithology have the same erosional soil and hence the same aspect on the images which prevents any differentiation. For such unknown areas, the use of MSS imagery is very helpful in wide recognition work and it is an interesting complement for synthesis study. However many cases clearly show that field checking is absolutely necessary. For this specific area, new remotely-sensed features are obtained, i.e. the N-S Rizal fault in north Palwan is clearly argumented and this may reinforce the importance of N-S faults in the area. The join pattern has been completed, although some elements of difficult interpretation require further investigations. Boundaries of the lithological units characterized and redated by field survey are more accurately mapped. Mindoro to the Asian mainland and its significance in the evolution of the South China Sea.
