This striking satellite photo shows a multicolor "fan" of folded rocks sculpted by a longtime collision between two of Earth's tectonic plates.

The geological feature, known as an imbricate fan, is located around 3 miles (5 kilometers) east of the town of Murgha Kibzai in Pakistan's Balochistan province. The photographed section of folded rocks measures around 9 miles (15 km) across, but the fan stretches up to 55 miles (89 km) from end to end, well beyond the area in this image.

The dramatic structure sits at an altitude of around 5,000 feet (1,500 meters) in the Sulaiman Range, a series of mountains that covers around 2,500 square miles (6,500 square kilometers) of Pakistan and Afghanistan. ("Sulaiman" means "of Solomon," in reference to the biblical figure King Solomon, and the range's largest peak is Takht-e-Sulaiman, which translates to "Throne of Solomon.")

This is one of several unique features that emerged along the boundary between the Eurasian and Indian tectonic plates, which have been colliding for more than 60 million years. At one point during this tectonic tug-of-war, the two plates became somewhat intertwined, allowing the fan to take shape, according to NASA's Earth Observatory.

"As India moved northward, it began to rotate in a counter-clockwise direction, wrenching the northwestern part of the Indian plate backwards into part of the Eurasian plate," Earth Observatory representatives wrote. "The countervailing forces put the rocks of the Sulaiman Range in a unique compressional vice, causing many of its faults to curve and stretch in convoluted ways."

The fan is made up of alternating layers of sandstone, which appear dark in the image, and limestone, which has a much lighter hue. These sedimentary rocks were formed by "thrust faults" that shot upward from the boundary between the Eurasian and Indian plates and became entangled as the boundary moved back and forth.

The satellite image is false-color, meaning it includes wavelengths of the electromagnetic spectrum that are not normally visible to humans. This helps to accentuate the differences between the two rock types, although they can also be easily distinguished with the naked eye. Pockets of vegetation appear in red throughout the image.

The photo is a small part of a larger, wide-field image (see above), which showcases several other intriguing geological features across the Sulaiman Range in false color.

Continental collision

The collision between the Eurasian and Indian plates became inevitable around 80 million years ago, when dinosaurs still ruled Earth, according to the Earth Observatory. At this point, the pair became locked on a collision course, with each plate moving more than 8 inches (20 centimeters) per year — around twice the speed of the fastest tectonic plates today.

Around 60 million years ago, the plates slowly slammed together. Normally, this would cause the smallest tectonic plate to sink below the other. However, the two plates' massive size meant neither receded. Instead, the continental crust along the boundary grew thicker, and the ground buckled, folded and pushed upward.

This process created not only the Sulaiman Range but also the Karakoram (a huge mountain range that spans the borders of China, India, Pakistan, Tajikistan and Afghanistan) and the Himalayas — the two tallest mountain ranges on Earth, according to the Earth Observatory.

This collision continued at full speed for around 30 million years, before eventually slowing down. However, the two plates are still technically colliding today, making the region a major earthquake hotspot.
