How Old is Mount Everest? The Geological History and Formation of the World's Highest Peak

The Geological Age and Formation of Mount Everest

Mount Everest, the world's tallest peak, is estimated to be 50 to 60 million years old, making it relatively young by geological standards. As a part of the majestic Himalayan range, Everest shares its origin story with these towering peaks, which were formed through significant geological processes.

Formation of the Himalayas

The formation of the Himalayas began approximately 40-50 million years ago with the collision of the Indian tectonic plate with the Eurasian continent. This tectonic activity, characterized by the northward movement of the Indian plate at a rate of 15 cm per year, resulted in the uplift of lighter rocks from ancient seabeds, creating the Himalayan range. A fascinating fact that illustrates this process is that the summit of Mount Everest is composed of marine limestone, indicating its underwater origins.

Ongoing Geological Processes

The geological forces that formed Everest continue to shape it today. The summit of Everest rises about a quarter of an inch higher each year due to the ongoing movement of tectonic plates. This continuous uplift ensures that the highest peak on Earth continues to rise, ever so slightly, year by year.

The Significance of Everest's Geology

Understanding the geological history and formation of Mount Everest not only highlights its grandeur but also underscores the dynamic processes that continue to shape our planet. Everest's relatively young age and its ongoing elevation are a testament to the powerful natural forces at work beneath the Earth's surface.

By delving into the geological story of Mount Everest, we gain a deeper appreciation for this iconic mountain and the remarkable natural phenomena that continue to influence its towering presence.

The Evolution of Mount Everest's Name and Height: A Detailed Survey History

Mount Everest was confirmed as the world’s highest mountain, replacing Kanchenjunga, which was previously considered the highest peak. Here's a detailed look at how Everest's name and height have evolved through various surveys:

19th Century Survey

The British began the Great Trigonometric Survey of India in 1802 to determine the location, heights, and names of the world’s highest mountains. Although incomplete initially, the survey resumed in 1847, focusing on the Himalayan peaks. The British Surveyor General of India, Andrew Waugh, conducted detailed measurements from the Sawajpore station. He and his subordinate, John Armstrong, identified a peak they called "peak ‘b’."

In 1849, Waugh sent James Nicolson to measure peak ‘b’. Nicolson's raw data indicated an average height of 9,200 meters (30,200 feet), suggesting it was higher than Kanchenjunga. This peak was then referred to as Peak XV. In 1852, an Indian mathematician and surveyor from Bengal identified Peak XV as the world’s highest peak using trigonometric calculations based on Nicolson’s measurements. The calculations were repeatedly verified, and the official announcement was made later.

20th Century Survey

The height of 8,848 meters (29,029 feet) was officially approved by Nepal and China. The Chinese Academy of Sciences and the State Bureau of Surveying and Mapping announced Everest's elevation as 8,844.43 meters (29,017.16 feet) with an accuracy of ±0.21 meters (8.3 inches), claiming it as the most accurate measurement. The team also measured a snow depth of 3.5 meters (11 feet), aligning with a net elevation of 8,848 meters. However, a debate arose between China and Nepal over whether to use the rock height (8,844 meters) or the snow height (8,848 meters). In 2010, both countries agreed to recognize Everest's height as 8,848 meters, with Nepal acknowledging China's rock height claim.

21st Century Survey

After years of calculations from the Great Trigonometric Survey, Andrew Waugh announced in 1856 that Everest (Peak XV) was 8,840 meters (29,002 feet). In 1865, Everest received its official English name. The height of 8,848 meters was first determined by the Indian survey in 1955 using theodolites and reaffirmed by a Chinese measurement in 1975, which measured the snow cap, not the rock head.

In 1999, an American Everest Expedition, led by Bradford Washburn, used GPS to secure the highest bedrock measurement. This determined a rock head elevation of 8,850 meters (29,035 feet) with a snow elevation 1 meter higher. Under Washburn's direction in the late 1980s, a more accurate topographic map of the Everest region was created using extensive aerial photography.

Understanding the evolution of Mount Everest's name and height offers a fascinating glimpse into the history and precision of mountain surveying, reflecting the dedication and advancements in geographic science over the centuries.

Geological Composition of Mount Everest: An In-Depth Look

Mount Everest, the world's highest peak, is a geological marvel composed of distinct rock formations, each separated by low-angle faults known as detachments. These formations have been thrust southward over each other, creating the complex structure of Everest as we know it today.

From the summit to the base, the three primary rock units of Everest are the Qomolangma Formation, the North Col Formation, and the Rongbuk Formation.

1. Qomolangma Formation: This formation extends from the summit down to the top of the Yellow Band, approximately 8,600 meters (28,200 feet) above sea level. Also known as the Jolmo Lungama Formation, it consists of greyish to dark grey or white Ordovician limestone, characterized by parallel layering and embedding. The formation also contains interlayered subordinate beds of recrystallized dolomite with argillaceous laminae and siltstone. High-angle faults disrupt the Qomolangma Formation, terminating at the low-angle normal fault called the Qomolangma Detachment.
2. North Col Formation: Situated between 7,000 meters (23,000 feet) and 8,600 meters (28,200 feet), the North Col Formation constitutes the bulk of Everest. The Yellow Band, which forms the upper part of this formation, lies between 8,200 meters (26,900 feet) and 8,600 meters (28,200 feet). This band consists of Middle Cambrian diopside-epidote-bearing marble and is distinguished by its yellowish-brown and muscovite-biotite phyllite or semischist composition.
3. Rongbuk Formation: Below 7,000 meters (23,000 feet), the Rongbuk Formation forms the base of Mount Everest. It comprises sillimanite-K-feldspar grade schist and gneiss, intruded by various sills and barriers of leucogranite. This formation represents the deeper layers of Everest's geological structure.

Everest's rocks are primarily sedimentary and metamorphic, faulted southward across continental crust formed by Archean granulites of the Indian plate during the Cenozoic collision of India with Asia. Recent interpretations suggest that the Qomolangma and North Col Formations consist of marine sediments, which accumulated within the continental shelf of the northern passive continental margin of India before its collision with Asia.

Understanding the geological makeup of Mount Everest not only provides insights into its formation but also enhances our appreciation of this iconic natural wonder.
