Getting there and getting around England

From North America, the cheapest and most convenient access to the Jurassic Coast is via one of London’s major airports. Nonstop service to Heathrow (LHR) and Gatwick (LGW) airports is available from many major U.S. cities.From London, the easiest way to get to (and around) the Jurassic Coast is by renting a vehicle, assuming you’re comfortable driving on the left side of the road. Because Gatwick is located on London’s southern outskirts, it offers the best escape to England’s southern coast from the hustle and bustle of the city.

Data-driven discovery reveals Earth's missing minerals

New discoveries in mineralogy, one of the oldest human endeavors, are arising from a new sort of mining—data mining. Mineralogists are applying statistical models and data science techniques to reveal previously unseen patterns and clues hidden in mineralogical databases, and to find undiscovered minerals.

Oceanic crust in all its glory

Our loop drive through the high Hajar Mountains boasted excellent exposures of every oceanic crustal layer. One good exposure of the sequence of mantle rocks is found in the hills surrounding Oman’s capital city Muscat. They consist of a variety of peridotite called harzburgite, which is the pyroxene-depleted residue left behind after basaltic magma is extracted. That extracted magma forms the oceanic crust, whose characteristic rock sequence is, from bottom to top: 1) dark, layered gabbro overlain by massive gabbro (the intrusive equivalent of basalt that comprises solidified magma chambers); 2) sheeted basaltic dikes (the conduits that transported lava from the magma chambers up to the ocean floor); and 3) bulbous pillow lavas, which form when basalt erupts directly into seawater.

Getting there and getting around Oman

Oman’s main gateway is Muscat International Airport (MCT), which offers service to most major Middle Eastern and European cities. There are no direct flights to Oman from North America; it’s usually most convenient to fly through Dubai, Doha, Bahrain or a major European city. Emirates, Qatar Airways, Gulf Air, Oman Air and Turkish Airlines are among those that offer connecting service.
