Thanks to all for a great year, to thanks to those who wrote articles and all the support you all have given to TravelingGeologist. Here’s to 2018!  The JOIDES Resolution tied up in Hobart. The Resolution is coming back to port this weekend and will be in Perth on Sunday after spending two months at sea as part of IODP Expedition 369. This project has been focused on understanding the relationship between climate and tectonics during the Cretaceous. Check our most recent article by Dr Lloyd White about this science cruise.

These features indicate that the base level is different between these to two rivers and that there has likely been a base level drop in the upper river.  Mount Rainier and Mount Hood (or Adams?) of the Cascade volcanic chain. Subduction of the Pacific Ocean creates a beautiful row of volcanoes. Prepare for a string of  pics from my flight from Seattle.  Amazing migmatite and hornblende-bearing pegmatite of the Zanhuang Complex of the North China Craton. The is the first hornblende pegmatite I have ever seen. In fact the first time I consider such a thing was possible. Anyone else seen something like this?  En route back to China! Looking forward to some Shanxi noodles!!
 A geologist in New York City doesn’t care about Broadway or overpriced tourist traps. The Manhattan schist is the only thing in NYC I need.  Shandongosaurus giganteus (found in and named after the Shandong province of China) is part of the Hadrosaur family one of the largest ornithischians. Hadrosaurs are well known for being found next to their nests and one in particular is known as the ‘good mother lizard’ (Maiasauras). I therefore dub Shandongosaurus ‘big momma’.  Beautiful river terraces somewhere over Idaho. There are two basic types of river terraces, fill terraces and strath terraces. As the name suggests fill terraces are formed by the deposition and subsequent erosion of alluvium. Strath terraces on the other hand are formed directly in the bedrock. It is hard (for me) to tell whether these are strath or fill, but it is clear these are asymmetric terraces (or unpaired) meaning that they only form on one side of the river valley.  Going to conferences is fun. Going to conferences in the autumn is better. #GSA2017 #Seattle  Tang Li and Hong Jun examining a garnet amphibolite in the southern Taihang Mountains of the North China Craton. The best fieldies anyone could ask for!!  The science party of the INGON cruise Leg 258b. We left Colombo Harbour with the RV Sonne on the 12th of July 2017. The aim of the cruise was to gather more subsurface data along the Sri Lankan continental margin. Once, India and Sri Lanka were attached to Antarctica. The break-up to spreading history is recorded on the margins of the continent and in the oceanic crust. With the magnetic data acquired during this cruise, we investigate the magnetic pattern and thus the age of the oceanic crust and the timing of the spreading history. The OBS stations record both reflected and refracted waves, giving inside in the crustal structure of the margin. Do the margins contain volcanic material? Where does the continental crust change to oceanic crust? The hydro-acoustic data provided information on the ocean floor, which in this case was quite flat except for one deep-sea channel. On the 17th of August 2017 the vessel docked again in the harbour of Colombo. (Text by Anouk Beniest. Photo by Wolfgang Borchert, 2017)
 The Aladaglar Mountains of Turkey with the Ulukisla basin in the foreground. In between the mountains and basin lies a major strike slip fault. The transpression and transtension along this strike slip fault has resulted in uplift of the mountains and subsidence of the basin. Read more about Derya’s adventures in Turkey on the link in the profile.  Magma disaggregation texture at Bingie Bingie point, New South Wales, Aus. The rubbly top of enclaves reflects magmatic disaggregation of the underlying gabbroic layer, whereas the upper gabbro has formed chilled bulbous pillows which have been injected by granitic veins (flame structures) which project several metres into the overlying gabbro. By Xiaofang He.  The venerable Mount St Helens erupted in 1980 killing 57 people and spreading ash across 11 states. It has since erupted nearly continuously building the large central dome visible in the crater.  Sometimes samples are too big to bring home so we need to strategically break, reassemble, choose our samples wisely.  Folds in the Zanhuang Complex in the southern Taihang Mountains of China 🇨🇳 Why is it that seeing folds never gets old?  The joys of being at sea. Spinner dolphins speeding our way. There are three marine mammal observers on board. During day-time they watch for whales, dolphins, turtles and other wildlife. Once the airguns are working for seismic data acquisition, the observers have to watch that no marine mammal comes to close to the vessel as it might damage their hearing and the orientation. Once a marine mammal is observed, a shutdown of the airguns is being requested by the observers until the animals are gone. (Text by Anouk Beniest, Photo by Marcus Bridge, 2017)
