Dendrochronological methods for reconstructing mass movements — An example of landslide activity analysis using tree-ring eccentricity
Silesian University of Technology - - 2012
Abstract Dendrochronological methods can be applied to the reconstruction of
different types of environmental events such as climate changes, fires, glacier
movements, floods, earthquakes, volcano activity. In the field of geomorphology
dendrochronology is increasingly frequently used for the absolute dating of
different types of mass-movements (rock falls, landslides and debris flows,
etc.). Tree...
Sự bào mòn nhanh chóng của dãy Himalaya Cao trong thời kỳ Pleistocen muộn, bằng chứng từ nhiệt địa chất OSL Dịch bởi AI
Silesian University of Technology - Tập 40 - Trang 304-310 - 2013
Quá trình phát quang kích thích quang học (Optically Stimulated Luminescence -
OSL) của thạch anh, với nhiệt độ đóng kín từ 30–35°C, kết hợp với Truy vết phân
hạch Apatite (AFT; nhiệt độ đóng kín khoảng 120°C) và phương pháp 40Ar-39Ar
(nhiệt độ đóng kín biotite khoảng 350°C), đã được sử dụng để xác định tuổi làm
mát từ các đá tinh thể cao thuộc dãy Himalaya Tây Arunachal (WAH). Dữ liệu tuổi

Infrared radiofluorescence (IR-RF) dating of middle pleistocene fluvial archives of the Heidelberg Basin (Southwest Germany)
Silesian University of Technology - Tập 38 - Trang 23-33 - 2011
The infrared radiofluorescence (IR-RF) dating technique was applied to eight
fluvial samples that were collected from two sediment cores at the Heidelberg
Basin located near Viernheim and Ludwigshafen in southwest Germany. Based on the
IR-RF derived ages of the samples it was possible to establish a chronological
framework for the Mid-Pleistocene fluvial deposits of the Heidelberg Basin. The
resul...
Investigation of the temporal change of the sources of Aeolian dust delivered to East Asia using electron spin resonance signals in quartz
Silesian University of Technology - Tập 40 - Trang 355-359 - 2013
The temporal change in the number of oxygen vacancies in quartz was investigated
by ob-serving the E1’ center in the atmospheric depositions collected at two
cities in Japan in the recent past. The depositions collected at Fukuoka in
March show the ESR intensities being correlated with the sum of the number of
the days, in the month, on which Kosa was observed while no such correlation was
found i...
Cretaceous aggregate and reservoir effect in dating of binding materials
Silesian University of Technology - Tập 40 - Trang 33-41 - 2012
Lime mortars may contain carbon from different origins. If the mortars are made
of totally burnt lime, radiocarbon dating yields the true age of building
construction. The presence of carbonaceous aggregates gives the so-called dead
carbon effect, which may generate older ages. Another source of carbon is
charcoal present in mortars. An attempt has been made to apply the radiocarbon
method to mort...
A lake fortress, a floating chronology, and an atmospheric anomaly: the surprising results of a radiocarbon wiggle-match from Āraiši, Latvia
Silesian University of Technology - Tập 41 - Trang 223-233 - 2014
An Iron Age timber settlement which, in view of the defensive structures
uncovered, is described as a lake fortress, on an island in Lake Āraiši,
north-eastern Latvia, was excavated in 1965–69 and 1975–79 by teams led by Jānis
Apals, who distinguished five construction phases. Dendrochronological analysis
produced a c. 100-year floating chronology for Norway spruce (Picea abies (L.)
Karst.) timber...
First note on marine-like cementation of Late Holocene beachrock, Iznik Lake (Turkey)
Silesian University of Technology - Tập 39 - Trang 76-83 - 2011
Micro-fabric characteristics and optically stimulated luminescence (OSL) dating
results are presented to discuss the controlling agents and timing of beachrock
cementation on the fresh-water Iznik Lake shoreline. The beachrocks are made up
of grain-supported polygenic conglomerate containing 20.42% carbonate with
encrusted grains, basically as micrite coatings, isopachous aragonite rims,
cryptocry...
Age constraints and denudation rate of a multistage fault line scarp: an example from Southern Italy
Silesian University of Technology - Tập 41 - Trang 245-255 - 2014
The morphological evolution of a carbonate fault line scarp from southern Italy,
generated by transpressional faulting and evolved by slope replacement, has been
reconstructed. 14C dating of faulted slope deposits (ages included between 18 ka
and ∼8 ka BP) have been performed to constrain the Late Pleistocene — Holocene
evolution of that scarp. Long-to short-term denudation rates have been also
ev...
Detailed protocol for an accurate non-destructive direct dating of tooth enamel fragment using Electron Spin Resonance
Silesian University of Technology - Tập 40 - Trang 322-333 - 2013
In the context of human evolution, fossil remains are too valuable to be
destroyed and any alteration should be kept to a minimum. The newly developed
protocol on fossil fragments has open the gate for ‘virtually’ non-destructive
ESR (Electron Spin Resonance) direct dating of human remains. The method allows
the separation of unstable and interfering signals that were responsible for
large dose un...
Multi-method luminescence investigations on quartz grains of different sizes extracted from a loess section in Southeast Romania interbedding the Campanian Ignimbrite ash layer
Silesian University of Technology - Tập 41 - Trang 1-14 - 2013
In this study we present luminescence investigations of four samples of loess
bracketing the Campanian Ignimbrite/Y5 tephra at the Rasova-Valea cu Pietre
site, on the eastern bank of the Danube River, southeastern Romania.
Investigations involved SAR-OSL dating on aliquots of fine (4–11 μm) and
medium-grained (63–90 μm) quartz, as well as single grain analyses on 125–180 μm
quartz. Luminescence da...
