4. Reconstructing
paleoseismic deformation, 2: 1000 years of great earthquakes at Chucalén, south
central Chile

•1000 year record of megathrust earthquakes and tsunamis
in south central Chile.
•The geological record underrepresents the frequency of
great earthquakes.
•Vertical coseismic deformation estimates vary between
earthquakes.
•Chucalén records net relative sea-level rise over the
last millennium.

5. 40Ar/39Ar ages and
residual volatile contents in degassed subaerial and subglacial glassy volcanic
rocks from Iceland

S.P. Kelleya, D.W. McGarvie
•New 40Ar/39Ar
ages have been determined for subglacially erupted glasses in Iceland
•Alteration,
hydration and mass-fractionation likely prevented age determination in some
samples
•These
disturbances are linked to micro-scale variability in measured volatile contents
•Water
contents in fresh glass can be used to estimate ice-thickness
6. Lead concentrations and isotope ratios in speleothems
as proxies for atmospheric metal pollution since the industrial revolution

•Study of
atmospheric metals from three Belgian stalagmites
•Reconstruction
of Pb pollution deposition over last 250 years
•Maximum Pb
concentrations are recorded from 1880 to 1905 AD, from 1945 to
1965 AD, and from 1975 to 1990 AD.
•Pb
isotopic composition used to identify the main sources of Pb
•The
predominant anthropogenic trace metal sources were coal consumption and
metallurgical activities.
