Maori legend tells that the boulders are remains of calabashes, kumaras and eel baskets that washed ashore after the legendary canoe, the Araiteuru was wrecked at nearby … These boulders are grey-colored septarian concretions, which have been exhumed from the mudstone enclosing them and concentrated on the beach by coastal erosion. Their spherical shape indicates that the source of calcium was mass diffusion, as opposed to fluid flow. [1][3][4], The composition of the Moeraki Boulders and the septaria that they contain are typical of, often virtually identical to, septarian concretions that have been found in exposures of sedimentary rocks in New Zealand and elsewhere. After the concretions formed, large cracks known as septaria formed in them. Supposedly this privately-owned island in Nova Scotia sits atop buried treasure or rare artifacts. This is demonstrated by studies of their composition; specifically the magnesium and iron content, and stable isotopes of oxygen and carbon. In Tasman Bay, off the northern coast of the South Island of New Zealand, you will find Tokangawh? Hudson, J.D., M.L. Wellington, New Zealand. Brown calcite, yellow calcite, and small amounts of dolomite and quartz progressively filled these cracks when a drop in sea level allowed fresh groundwater to flow through the mudstone enclosing them.

The Moeraki Boulders lie scattered along Koekohe Beach in New Zealand's South Island. Unlike the Moeraki boulders, some of these concretions contain the bones of mosasaurs and plesiosaurs.[3]. Even today, there are still boulders remaining in the mudstone that will, eventually, fall on to the beach as they come lose due to erosion! These cracks radiate and thin outward from the centre of the typical boulder and are typically filled with an outer (early stage) layer of brown calcite and an inner (late stage) layer of yellow calcite spar, which often, but not always, completely fills the cracks. The Moeraki Boulders are huge spherical rocks on Koekohe Beach on the Otago coast of New Zealand’s South Island.

The larger boulders, 2 metres (6.6 ft) in diameter, are estimated to have taken 4 to 5.5 million years to grow while 10 to 50 metres (33 to 164 ft) of marine mud accumulated on the seafloor above them. In more recent times they have become a popular tourist attraction. Coleman, B.A. These boulders are actually concretions that have been exposed through shoreline erosion from coastal cliffs. [5] The boulders were described in 1850 colonial reports and numerous popular articles since that time. 1. Topo50 / 1:50,000; Topo250 / 1:250,000 References: Appearing like a congregation of planets, the stones, with their sheer size and nearly perfect shapes, give birth to an alien landscape. The erosion by wave action of mudstone, comprising local bedrock and landslides, frequently exposes embedded isolated boulders. Vyacheslav Argenberg Getty Images.

[3][5][6], The most striking aspect of the boulders is their unusually large size and spherical shape, with a distinct bimodal size distribution. This legend tells of the rocky shoals that extend seaward from Shag Point as being the petrified hull of this wreck and a nearby rocky promontory as being the body of the canoe's captain. The Moeraki Boulders are unusually large and spherical boulders lying along a stretch of Koekohe Beach on the wave-cut Otago coast of New Zealand between Moeraki and Hampden.They occur scattered either as isolated or clusters of boulders within a stretch of beach where they have been protected in a scientific reserve. GP Books. or Split Apple Rock. Approximately one-third of the boulders range in size from about 0.5 to 1.0 metre (1.6 to 3.3 ft) in diameter, the other two-thirds from 1.5 to 2.2 metres (4.9 to 7.2 ft). The biggest legend is that a formation of boulders, called “The Money Pit,” which hides treasure from pre-1795 that has yet to be found. Early morning and late afternoon are the prime times for photography, when brilliant soft sunlight is cast across the rocks; making for spectacular photographic opportunities. J. R. Boles, C. A.

R., C. A. Landis, and P. Dale, 1985. ... also known as Golden Rock, is a well-known Buddhist pilgrimage site in Mon State, Myanmar. Some of the boulders weigh several tonnes and the largest ones can be over 2 metres wide! Detailed analysis of the fine-grained rock using optical mineralogy, X-ray crystallography, and electron microprobe has determined that the boulders consist of mud, fine silt and clay, cemented by calcite. The picture is now in the Alexander Turnbull Library in Wellington. The Moeraki Boulders range from 5 ft to 7 ft high (1.5 m to 2 m), and pepper the beaches, cliffs, and shoreline throughout Koekohe. The Moeraki Boulders are unusually large and spherical boulders lying along a stretch of Koekohe Beach between Moeraki and Hampden in New Zealand. [1][3][4], Neither the spherical to subspherical shape or large size of the Moeraki Boulders is unique to them. Watch the video below for a short introduction and some fascinating facts about the Moeraki Boulders! During the 19th century, ideas about Aryan migrations became popular and these were applied to New Zealand.

Legend has it that millions of years ago, the gods were fighting over a golden apple. The Moeraki Boulders; anatomy of some septarian concretions. Most are spherical or almost spherical, but a small proportion are slightly elongated parallel to the bedding plane of the mudstone that once enclosed them. The boulders are made of mud, clay, and fine silt, and are held together by calcite. They originally started forming in ancient sea floor sediments around 60 million years ago, and the largest boulders are estimated to have taken about 4 million years1 to get to their current size. Like the Moeraki Boulders, the Koutu Boulders are large, reaching 3 metres (10 ft) in diameter, and almost spherical. These concretions occur as both spherical cannonball concretions and flat, disk-shaped or oval concretions. Edward Tregear's The Aryan Maori (1885) suggested that Aryans from India migrated to southeast Asia and thence to the islands of the Pacific, including New Zealand.. [1][4], The rock comprising the bulk of a boulder is riddled with large cracks called septaria that radiate outward from a hollow core lined with scalenohedral calcite crystals. The outside rims of the larger boulders consist of as much as 10 to 20% calcite because the calcite not only tightly cements the silt and clay but has also replaced it to a significant degree. [7][8] Similar septarian concretions have been found in the Kimmeridge Clay and Oxford Clay of England, and at many other locations worldwide. Map; Regions; Legend . The main body of the boulders started forming in what was then marine mud, near the surface of the Paleocene sea floor. 11 … Rare Moeraki Boulders have a very thin innermost (latest stage) layer of dolomite and quartz covering the yellow calcite spar. We showcase some of the very best photos of the Moeraki Boulders and the surrounding area on our Photos page.

Maori legend tells that the boulders are remains of calabashes, kumaras and eel baskets that washed ashore after the legendary canoe, the Araiteuru was wrecked at nearby Shag Point (Matakaea). Similar large spherical concretions have been found in many other countries.
