Geocache Description:


What is a CAPE?

A cape is a headland or a promontory of large size extending into a body of water, usually the sea. A cape usually represents a marked change in trend of the coastline. Their proximity to the coastline makes them prone to natural forms of erosion, mainly tidal actions.

Cape Raso

Cabo Raso is a beautiful and scenic part of the Portuguese west coast of Portugal and is located in the parish and municipality of Cascais, in the district of Lisbon. In the middle of the cape is the Cape Raso Lighthouse and the São Brás Fort of Sanxete. It is relatively close to the village of Cascais, in the extreme southwest of the Estoril Coast, and a few kilometres south of Cabo da Roca.

oneThe rock types are reef limestones of Lower Cretaceous age striking E-W cut occasionally by igneous dykes.

Registration requirements

Question 1 - What kind of rock outcrops in GZ? (if it's whitish it may be limestone. If it's green it might be malachite. If it's got black and orange spots, it's out of this world. If it's pink, it is granite)

Question 2 - Is there any obvious fracturing in the surroundings?

Question 3 - If the answer to 2 is positive, what is the main orientation of the fractures? If not, go to question 4.

Question 4 - Is there any basalt outcrops that can be seen from GZ? (The basalt is a very dark, fine-grained rock).

Optional Task: Landscape photos sff.

If you have worked out all the answers, please send them to my address via my profile page. You must do this to validate your find.

Watch out for waves on stormy days!!!!!!!

  

O que é um cabo?

Um cabo, promontório, ponta ou pontal é um acidente geográfico formado por uma massa de terra que se estende por um oceano ou mar que lhe está adjacente. Um cabo, em geral, tem mais importância que um twopromontório, e muitas vezes exerce influência sobre correntes costeiras e outras características oceanográficas de seu meio. Um cabo, portanto, é idealmente uma península estreita mas isto varia, como poderão observar nesta EC.

Cabo Raso

O Cabo Raso faz parte da costa ocidental marítima portuguesa e situa-se na freguesia e concelho de Cascais, no distrito de Lisboa. Em pleno cabo situa-se o Farol do Cabo Raso e o Forte de São Brás de Sanxete. Está relativamente perto da vila de Cascais, no extremo sudoeste da Costa do Estoril, e poucos quilómetros a sul do cabo da Roca.

Geologicamente é composto por calcários recifais do Cretácico Inferior (Hauteriviano – Barremiano; 136.4 to 125 M.a.).three

 

Requisitos de registo

Pergunta 1 – Qual o tipo de rocha no GZ?

Pergunta 2 – Existe alguma fracturação evidente na envolvente?

Pergunta 3 – No caso da resposta a 2 ser positiva, qual a sua orientação? No caso de ser negativa, passe à pergunta 4.

Pergunta 4 – Existe algum dique de basalto que se veja do GZ? (o basalto é uma rocha de grão fino e muito escura).

Tarefa Opcional: Fotos da paisagem sff.

 

Depois de fazeres o teste envia-me as respostas a estas perguntas. Esta é a única maneira de  validar o registo nesta cache.

Cuidado com as ondas em dias de tempestade!!!!!!!

 

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.
