Research Abstract

This study aims to establish the late Quaternary seismo-tectonic movement in the Circum Pacific area. Field work was carried out in 1989 in the northern Chile and southeastern South Island, New Zealand. Quaternary chronology and rate of deformation will be discussed after the dating of samples by ESR, aminoacid and ^<14>C method. Main results are as follows:
New Zealand: (Kaikoura Peninsula: 1) Four steps of Pleistocene marine terraces and their progressive northwestward tilting were identified. 2) Episodic uplift during the Holocene are deduced from subdivided Holocene marine terraces.
Coastal area from Kaikoura Peninsula to Cape Campbell: 1) Two steps of Pleistocene marine terraces and their northward tilting were identified. 2) One marine terrace near Long Point indicates a downwarping. 3) Holocene marine terrace reaches 20 m in height suggests probable coseismic uplift.
Big Lagoon and Lake Grassemere: 1) An apparent upper limit of estuarine deposits is 2 m above sea level at the highest indicating that these areas are subsiding. No Holocene marine terraces exist.
Chile: Tongoy and La Serena: 1) A series of marine terraces were identified. 2) Differential uplift is observed in both areas. 3) Normal faults dislocating marine terraces are mapped. 4) Quebrada Teniante Fault shows repeated activities during the Quaternary and an apparent left-lateral offset. 5) No subdivided Holocene terraces exists.
Mejillones Peninsula: 1) Marine terraces, up to ca. 700m in height and composed of ca. 10 steps, show a continued uplift for long time. 2) many normal faults dislocate marine terraces and alluvial fans progressively.
