In this mini-review, we shall first cover a short history of the discovery of chitin isolated from
sponges; as well as its evolutionarily ancient roots. Next, we will delve into the unique …

ABSTRACT A number of hydrothermal vent sites exist on the summit of the Loihi Seamount,
a shield volcano that is part of the Hawaiian archipelago. The vents are 1,100 to 1,325 m …

The oxygen isotope composition (δ18O) of marine sedimentary rocks has increased by 10 to
15 per mil since Archean time. Interpretation of this trend is hindered by the dual control of …

The uppermost Permian strata of the Abadeh section in Iran consist of 56 m of skeletal
limestone (Abadehian), that grades upward into 18 m of grey, bioturbated lime mudstone …

Middle Ordovician iron ooids in the Upper Yangtze region of South China are composed
mainly of hematite and/or chamosite, found in mixed siliciclastic and carbonate successions …

Abstract The Jurassic System (199.6-145.5 Ma; Gradstein et al. 2004), the second of three
systems constituting the Mesozoic era, was established in Central Europe about 200 years …

One remarkable discovery in Mars geology is the extensive Meridiani iron formation.
Although thermal oxidation mechanisms have been proposed for its origin, geomorphology …

The Cenozoic tectonic evolution of Central Europe was governed over long periods of time
by far-field stresses resulting from continent collision in the Alps (which is still ongoing) ridge …

Abstract Carbonate platforms across Western Europe were superseded at the Middle–Upper
Jurassic (Callovian–Oxfordian) boundary either by alternating marl–limestone and …

We report the structural geometry and facies architecture of a small diapir-related carbonate-
dominated basin from the Jurassic rift of the Moroccan High Atlas. The Azag minibasin is a …
