 First sunset in Iceland! Icelandites here we come!!  Enjoying some of the local outcrops (dolerite dykes intruding Archean granodiorite) in the Perth hills with the chidlers. You can see the paleomagicians have already been here...  Road side outcrop 30 km from the town of Kurmuk and the Sudanese border. These well foliated granites, granodiorites and metasediments provide a great section to interpret the relationships between these units.

The Ore Obelisk in Perth signifying the tremendous natural resources on which the economy of Western Australia depends. From the top to bottom: Diamond Magnesite (Magnesium) Manganese Ore Quartz Dolerite (Silver) Cassiterite (Tin) Hematite (Iron) Galena (Lead) Supergene (Nickel) Quartz Dolerite (Gold) Spodumene (Lithium) Bauxite (Aluminium) Chalcocite (Copper) Jaspillite (Iron) Azurite and Malachite (Copper) Hematite (Iron) All of these skewered by a drill stem representing oil off the NW Shelf.  From the monasteries to the people to even the cute dogs, geology is not the only thing to see in Bhutan! Photos by Stacy Phillips.  The #MountainsAreCalling and I must go!
 Had a lovely few days in Finland. Good rocks, good weather (mostly), and the best reindeer burger I have ever had!!!  The Mansehra granite near Susal Gali, Pakistan is medium to coarse-grained and porphyritic rock containing K-feldspar phenocrysts of variable amount and size (2-10 cm). The groundmass is composed of K-feldspar, plagioclase, quartz, and biotite with subordinate muscovite; zircon, apatite and tourmaline are accessory minerals.

These rocks lie within the Palghat-Cauvery shear system, a suture between Neoproterozoic India and the Madurai Block to the south. Photo by Diana Plavsa.  Another important stop of our field trip is in the Andriamena area, where a cluster of chromite deposits and occurrences are hosted in mafic-ultramafic intrusions. Although export of chromite ores coming from this area has been essential for Madagascar’s economy, ages and genesis of the hosted intrusions are very poorly known. Ongoing research about these deposits will aid in understand the timing and petrogenesis of these deposits. Read more in our most recent TG article.  The lush forests above Gasa, Bhutan and the valley and route north to the high settlement of Laya. Photo: Stacy Phillips. Despite the country being the size of Switzerland, Bhutan has the steepest elevation profile from highest to lowest point of any country in the world (so I have been told). This crazy gradient manifests itself in some pretty jaw-droppingly steep terrain, which makes getting around a bit tricky, to say the least. Enjoy bumping along a rocky track for days on end and trekking up steep hills to reach your field site? If so #Bhutan is the country for you.

 Who's up for a garnet pegmatite? Pretty solid first sample in Finland!  🇮🇩 Indonesia boast the youngest mountain range on the planet. As Australia drifts northward it collides with and subduction beneath Indonesia. In this photo (taken by Ron Harris), the recently uplift coral terraces can be seen in the distance on the island of Sumba. Eventually, the 'Banda Range' as Harris calls it will be similar to the Himalaya as Australia continues to move northward. Photo by: @ramelau1  The PhD of Diana Plavsa involved investigating the geology of southern India in the equivalent of a section through a 550 Ma old Tibet, with the top 30kms removed! Pretty amazing, and the rocks are amazing as well, with many beautiful metasedimentary pelites, some of these are so rich in garnet that they glisten in the sun and you can see the red colour from hundreds of metres away. This peak was a massive batholith of charnockite, that is a granite with orthopyroxene.  Madagascar, an enigmatic island country separated from mainland Africa by the Mozambique Channel, is made up of a Precambrian shield in the eastern two-thirds and Phanerozoic sedimentary and igneous rocks covering the western third. In the past decade, its significant potential for economic metal deposits has stimulated many oversea geologists to set foot on this mysterious land to conduct geological mapping and resource exploration. It was within this context that my first opportunity to access the Malagasy geology was supported by the China Geological Survey. ...our situation in the field was not so positive, and most of the mid-Neoproterozoic rocks in this area are deeply weathered and overlain by thick lateritic soil.

Heavily retrogressed and with very little evidence of granulite mineralogy, this mafic amphibolite, with large garnets, shows interesting melt-rock relationships with large amphibole porphyroblasts. Photo: Stacy Phillips. Read more about these mafic granulites in a recent article by Eleni Wood. Link in profile.  Eleni enjoying the spectacular views of the Bhutanese #Himalaya.
