Geocache Description:


Boudinage is a geological term for sausage-shaped structures formed by extension. 

Essentially, these are structures thta are also called pinch-and-swell for obvious reasons as you see from the image below.

The EarthCache

The narrow street makes fixing your position very difficult but you want to be in the corner of the alleyway below Rua do Alecrim next to the arch, therefore, standing in the pink road you need to face south and search next to the alleyway a greenish stone wall with marble tiles - See the image below and search for the blocked out squares X and Y in the image below:

On the basis of the observation of this tile, you need to answer the following questions:

  1. Do you see boudinage or pseudoboudinage in both squares X and Y?
  2. How many boudins do you see in the dark layer in square X?
  3. How many boudins do you see in the dark layer in square Y?
  4. What is the shape of these boudins?

Please send me the answers via my profile. If wrong, I  will get back to you. Thank you for visiting!

Boudinagem é o processo de deformação sofrido por camadas, ou bandas  mais competentes que se fragmentam em forma de boudins (salsichas) ao serem estirados dentro de  material rochoso mais dúctil quando o conjunto sofre esforços extensionais.

A EarthCache:

A rua estreita torna muito difícil fixar a tua posição, mas  queres estar na esquina do beco abaixo da Rua do Alecrim ao lado do arco. Portanto, parado na rua cor de rosa, precisas a olhar para sul e procurar junto ao beco uma parede com ladrilhos de mármore esverdeados - vê a imagem abaixo e observa os quadrados X e Y bloqueados na imagem:

Para validares o teu FOUND, precisas de responder correctamente às seguintes perguntas:

  1. Vês boudinage ou pseudoboudinage em ambos os quadrados X e Y?
  2. Quantos boudins vês na camada escura no quadrado X?
  3. Quantos boudins vês na camada escura no quadrado Y?
  4. Qual é a forma desses boudins?

Por favor, envia-me as respostas através do meu perfil. Se as respostas estiveram erradas, logo entro em contacto. Obrigado pela visita.

 

 

The most exciting way to learn about the Earth and its processes is to get into the outdoors and experience it first-hand. Visiting an Earthcache is a great outdoor activity the whole family can enjoy. An Earthcache is a special place that people can visit to learn about a unique geoscience feature or aspect of our Earth. Earthcaches include a set of educational notes and the details about where to find the location (latitude and longitude). Visitors to Earthcaches can see how our planet has been shaped by geological processes, how we manage the resources and how scientists gather evidence to learn about the Earth.
