Understanding Northern Ireland's Rocky Coasts

The Geological Survey of Northern Ireland (GSNI) is proud to be part of the CMAP Project, working with partners to better understand and protect our coastal environments.

Through the project, GSNI is focusing on three rocky coastal sites at Downhill, Cushendun and Kearney investigating the processes that shape these dynamic coastlines and how they may respond to future environmental change.

We're also engaging with local communities and citizen scientists, helping people connect with the geology on their doorstep and contribute to a better understanding of coastal change.

By combining scientific research with community engagement, we are helping to provide the evidence needed to support the sustainable management of Northern Ireland's coasts.

A huge thank you to all our project partners. Together, we're building a better understanding of our coasts for the benefit of communities, nature and future generations.

🪨 Geology on Your Doorstep: Exploring Belfast’s Building Stones 🏛️

To celebrate International Geodiversity, we recently led a Building Stones of Belfast walk for colleagues from the Department for the Economy, welcoming around 30–40 participants to explore the fascinating geology beneath our feet and all around us!

The walk highlighted the connections between Belfast’s geology, history and economy, revealing how the stones used in our buildings tell stories of the city’s past, its development and its connections to the wider world.

From rocks sourced here in NI, to building stones from across the UK and further afield internationally, Belfast’s built environment showcases an incredible diversity of geological materials — each with its own story to tell.

This year’s International Geodiversity Day theme, “Geology on Your Doorstep”, was a perfect reminder that you don’t have to travel far to discover the importance of geology. Sometimes, all you need to do is look at the buildings around you!

A big thank you to everyone who joined us for the walk and helped celebrate the role of geodiversity in shaping the places where we live and work.

🌍 International Geodiversity Day 2026: Geology on Your Doorstep

Geology is all around us, shaping the places where we live, work and explore.

NI may be small, but it is home to an extraordinary range of geodiversity. From the ancient rocks of the Sperrin Mountains, formed over 650 million years ago, to the iconic basalt columns of the Giant's Causeway; from the rugged Mourne Mountains, once molten granite deep within the Earth, to the drumlin landscapes that define counties Down, Armagh and Fermanagh, our geological heritage tells a remarkable story.

Along the Antrim Coast, evidence of volcanic activity can be seen in dramatic cliffs and lava flows. In Fermanagh, limestone landscapes have been carved into caves, rivers and karst features that continue to evolve today. Around the shoreline of county Down, ancient rocks record the assembly of continents, while our peatlands, river valleys and glacial deposits reveal the powerful forces that have shaped Northern Ireland more recently.

This rich geodiversity does more than create spectacular scenery. It provides the foundations for nature, influences where we build, supplies essential resources and helps us understand environmental challenges ranging from climate change to landslides and coastal erosion.

This International Geodiversity Day, take a moment to discover the geology on your doorstep. Every landscape has a story millions of years in the making.

📸 Precambrian (late Neoproterozoic) rocks that underlie much of the Sperrin Mountains (650-600 million years old)
📸 Palaeogene (60 million years old) columnar basalt of the Giant's Causeway
📸 Palaeogene granite tor of Slieve Binnian in the Mourne Mountains
📸 Quaternary drumlin landscape of Strangford Lough
📸 Palaeoegene flood basalt overlying Cretaceous (85-65 million years ago) white limestone at Garron Point
📸 Pollnagollum Coolarkan cave formed within Carboniferous (340 million years old) limestone in Co. Fermanagh
📸 Silurian sedimentary rocks exposed at Ardglass (445-410 million years ago)

⭐️ We’re absolutely delighted to have a triple win at the 2026 All-Ireland Sustainability Awards!

We were shortlisted in three categories — and we’re incredibly proud to have won all three:

🏆 Education for Sustainability
🏆 Green Marketing & Stakeholder Engagement
🏆 One to Watch – awarded to our Senior Energy Geologist, Michael MacKenzie

These awards recognise the work we’re doing across GSNI to support sustainability, innovation and positive impact through geoscience.

From engaging and educating the public, to supporting climate resilience and the energy transition, we’re proud of the contribution our team is making — and it’s fantastic to see that work recognised on an all-island stage.

A huge congratulations to Michael and to everyone who has helped make these achievements possible. These awards are a reflection of the passion, expertise and hard work of our whole team. 👏

We’re proud of what we’ve achieved and excited to keep building on this work. 🌍

The seventh webinar in the 2026 Northern Ireland Geothermal Webinar Series is taking place on Thursday 24th September at 16:00-17:00 BST.

Hester Claridge, PhD Researcher in Geothermal Energy - will present on FindHeat.

FindHeat is a new Horizon Europe R&D project, involving six research institutions and five industry partners, which aims to shift geothermal exploration towards geothermal resource and exploitation concepts that have inherently low technical and economic risks. This webinar will look at how the FindHeat project will develop a novel, conceptual model-based geothermal exploration workflow.

We hope you can make it, and we look forward to joining you online. Please make sure you register via the Eventbrite link below:

🪨💧 International Day of Caves and Karst

Today marks the very first International Day of Caves and Karst, following its approval by UNESCO in 2025.

This new international observance highlights the importance of caves and karst landscapes — remarkable geological environments shaped by the interaction of water, rock and time. They are important not only for understanding landscape evolution and the geological record, but also for groundwater resources, biodiversity and cultural heritage.

NI has an impressive variety of karst features, developed in rocks ranging from Carboniferous limestone to Cretaceous Ulster White Limestone.

📍 Marble Arch–Marlbank, Co. Fermanagh
One of NI’s best-developed karst landscapes, where Carboniferous limestone hosts an extensive cave system and underground drainage network, including the world-famous Marble Arch Caves.

📍 Boho, Co. Fermanagh
A landscape of caves, limestone gorges, sinking streams and other karst features. Boho Cave itself is a joint-controlled maze developed within Carboniferous limestone.

📍 Black Burn, Co. Antrim
An active cave system developed in the Cretaceous Ulster White Limestone. Here, surface water sinks underground where the Black Burn crosses the contact between basalt and limestone, demonstrating how geology influences the movement of water through the landscape.

📍 Linford, Co. Antrim
A notable example of surface karst, with dolines, sinks and a dry valley developed in limestone beneath the Antrim Plateau.

📍 Drumarg, Co. Armagh
A Carboniferous limestone cave system demonstrating that karst development extends beyond the better-known cave landscapes of Fermanagh and Antrim.

📍 Binnawooda, Co. Tyrone
An unusual example of karst developed in calcareous sandstone — recognised as the only known example of sandstone karst in NI.

From extensive underground cave systems to subtle features in the landscape, karst records the long-term interaction between bedrock, groundwater and geological processes.

On this inaugural International Day of Caves and Karst, we’re celebrating the geology beneath our feet — and the fascinating world hidden below the surface. 🔎🪨💧
