フェニックスガイド 文例 By 結城さん

The Phoenix Fold Those folded rocks consist of sandstones or mudstones. As you know, they are formed by sands and muds that flowed form a river mouth to deep sea ground and piled up with taking long-long times to be firm, and finally become rocks. Those rocks are called sedimentary rocks and they are normally flat unless they are having something strong pressure. This Phoenix Fold shows us unusual shape. Why? Because they had enormous pressure by submarine volcanic activity and crustal activity, before they have been firm in the deep sea and they forced to bend like present shapes. It is said that a incident occured about 30 million years ago. This bed has gradually lifted up by the tectonic movement and come up to the surface. This site is very famous for us to observe beautiful shape of the fold. Please imagine how the earth has made dynamic activity, seeing this Phoenix Fold.

・地球は10数枚のプレートで覆われていることはご存知と思いますが、この約 80km 沖の
Hello, welcome to our Nanki-Kumano Geopark.
My name is Jimbo Keishi. I am very glad to have a chance to guide you today.
Please call me Keishi.
Today, we are going to visit one of would-famous geosite Phenix Fold by boat.
Before starting our tour, I would like to explain key points because engine noise would disturb
my words.
Phenix Fold has such curious figure as this photo shows. Foe what made such a figure?
As you know, the earth surface covered 10 or more plates. At the point of about 80km off the
coast, two plates, one is continental plate, and the other is sea plate, conflicts under deep
Please look this figure and animation. At the result of very longstanding conflict, the sand and
mud deposit on the deep seabed had been run upon continent and folded. That is the reason
why Phenix Fold was made.
The name Phenix is come from near place.
Well, let's start our tour. Thank you.

高池の虫喰岩 Mushikui-Iwa Rock
蜂の巣のような不思議なかたちの岩ですね。地元では虫が食べたような岩、虫喰岩と呼んでいます。何がこんなかたちにしたのでしょうね? ハチでしょうか?魔物でしょうか?
岩の上の方を見てください。小屋のようなものが見えますが、 人の住居ではなく、今から200年近く前にここを訪れた修験者が人々の幸せを願って木の仏像を納めた小屋です。今は仏像は岩の下に移されています。

Look! What a fantastic honeycomb rock ! People call this “worm-eaten rock”. What made such a fantastic shape ? Bees or monsters?
This rock is a kind of igneous rock, and a part of long wall of huge caldera (Kumano-caldera) that appeared about 14 million years ago.
This wall is said to be the largest rock dike in the world. It is said the volcanic ash from Kumano- caldera would lower world temperature about 10 degrees centigurade.
We will visit the famous rock Ichimai-Iwa Monolith later. It located at the west end of the dike.
Please look up this rock, you would find something like a hut. That is not a hut for human residence but for buddha statues.
They were made by a visiting yamabushi(ascetic trainer) praying for people's happiness about 200 years ago. Now, the buddha statues were moved on the ground, so we can see them.

付加体 (現地研修会より)

付加体 (現地研修会より)

下にスライドします。 深海で作られた地層が陸地を作ります。

大陸プレートと海洋プレートの移動により、さまざまな砂と堆積物が押し合わされ、紀伊半島を構成する3つの陸塊の1つを形成しました。 これは付加体と呼ばれます。

水は山に落ち、地面に吸収されます。 雨水は地面から湧き出て、山を蛇行して新しい川を形成します。 これらの川は堆積物を運び、堆積してデルタを形成します。

Sliding down. Land made from deep sea. Made from Shallow sea

Because of the shifting of the continental and oceanic plates, various sand and sediments were pushed together, forming one of the three land masses that make up the Kii peninsula. This is called an Accretionary Prism.

Water falls in the mountains and is absorbed into the ground. The rainwater wells up from the ground, and snakes down the mountain, forming new rivers. These rivers carry sediments, which accumulate to form deltas.

It is a hot spring resort that was discovered in the middle of the Edo period when Shirasagi healed a wound on his leg. Like Shirahama hot springs, it is located on the northern extension of Karekinada arc-shaped dike and springs from the upper layer of the Tanabe Group.

The upper layers of the Tanabe Group deposited in the forearc basin are distributed. In Mikusazaki, you can observe the sedimentary structures peculiar to the strata deposited in the shallow sea, such as cross-bedding and ripple marks. In addition, fossils such as shellfish, whales, and crabs have been discovered. On the opposite bank of the harbor, you can also observe the mud diapir, which once had mud rising hundreds of meters in the stratum.

The exquisite striped pattern of the alternating layers of sandstone and mudstone in the upper part of the Tanabe Group deposited in the forearc basin is impressive. Sedimentary structures formed by transporting sand, etc. mainly due to tidal currents and waves develop, and the characteristics of strata deposited in shallow water can be observed. You can also see trace fossils.

This rock wall consists of thick sandstone and conglomerate formations in the upper part of the Tanabe Group, and "insect-eating" weathering is often seen in the conglomerate part. Many dents are densely packed in the rock wall like a honeycomb. This honeycomb-like weathering is called tafoni and is thought to have been caused by the dissolution and precipitation of salts in the formation.

In Gongenzaki, mudstone dikes with muddy lower layers intruding into the upper layers of the Tanabe Group develop. At the time of the formation of the Tanabe Group, mud deep underground was liquefied in the wake of an earthquake, and it is thought to be a dike extending from the mud diapir that cut into the upper strata. It is a valuable place where you can observe mudstone dikes three-dimensionally from the wave-cut platform to the sea cliff.

You can see the uncorfomity between the Otonashi River prism and the Kumano Group. The Kumano Group is a stratum deposited in the forearc basin formed on the Otonashi River accretionary prism, and there is a time gap of more than 30 million years between them. The Otonashi River accretionary prism is a muddy alternating layer, and the Kumano Group is a conglomerate / sandstone layer. There is an outcrop along the forest road connecting the villages of Sasabi and Kuju.

It is a valley where the Otonashi River accretionary prism is distributed. You can see alternating layers of sandstone and mudstone deposited in the submarine fan of the trench, crush zones associated with accretionary prism thrusts (low-angle reverse faults), and folds. In the area where the mudstone layer is distributed, the valley width is wide due to lateral erosion, and the village of Sasabi is formed.

The geological boundary of rhyolite (granodiorite) formed from the Kumano Group and the magma that penetrates it is exposed. It is a sheet-shaped igneous rock vein formed by magma penetrating at a low angle. Columnar joints develop on the rock wall of the Kumano River (Mt. Yotsume) due to the contraction of magma during cooling, forming a characteristic landscape in the Kumano River canyon. It is the southernmost body of Omine granitic rocks distributed along the Omine Mountains.

It is a shrine without a shrine building where Shiko valley joins the Kumano River. It enshrines the giant rocks on the hillside formed by the collapse of the thick sandstone layer in the upper part of the Kumano Group deposited in the forearc basin. Since the coal seam of the Kumano coalfield is displaced, it is estimated that a fault will pass in the east-west direction around this area, and it is possible that a collapse occurred along this fault.

It is a coal layer with a thickness of about 20 cm sandwiched between the upper layers of the Kumano Group. Coal has a metallic luster and is easily distinguishable from other formations. This coal layer is a coal layer that was mined by the nearby Mikuma Coal Mine, but the area between them is cut by a fault. Seven coal mines in the Kumano coalfield were operating in this area.

It is a shrine without a shrine on the banks of the Akagi River. A shrine without a shrine is one of the characteristics of the sanctuary in Nanki Kumano. It enshrines a group of giant stones on the banks of the river, which was formed by the collapse of the thick sandstone formation of the Kumano Group. This thick sandstone layer is the upper sandstone layer of the Kumano Group deposited in the forearc basin. Around the end of the Taisho era, it was enshrined at Takakura Shrine at Hitari.

The anti-road entrance, smelter ruins, and slag deposits, which are thought to be before the modern mining industry, remain on the left bank of Shirikendani. The yakimono used for ore smelting is lined up in an orderly manner with 10 units in the upper and lower stages, and there are traces of 4 units in the 2nd stage on the upstream side. The record that Nachi's copper was presented to Toyotomi Hideyoshi's "Tensho Tsuho" is the first record that remains today.

It is a boulder dedicated to eight people who were sacrificed by the debris flow that occurred in the late Edo period (1846). This boulder itself is rhyolite (granodiorite) that has flowed down due to debris flow. In the Irokawa area, there are records of eight debris flow disasters that have occurred since the middle of the Edo period.
